Genome Surprise
Catskul writes "Along with the news that the polished and (more nearly) complete human genome being published Monday, comes a surprising observation about the genome: We have substantially fewer genes than expected; between 27,000 and 40,000 as compared to an original estimate of 140,000." Update: 04/14 01:22 GMT by T : For everyone who can't look at a Z, headline updated with an S in "surprise."
This is why scientists are rebuking the French company's (Cloneaid?) claims that they have already cloned a human.
I dont like it when people think about what I think (say). Rather I try to make them think like I think.
Ingredients
1 genome (preferably human)
4 eggs
1/4 cup flour
1/2 teaspoon baking powder
1-1/2 teaspoons dry mustard
1 cup cottage cheese
1 cup shredded Jack cheese
1 cup shredded cheddar cheese
3 chopped peeled green chiles
One 16-ounce package frozen hash browns
Shaker of paprika --dust top of casserole just before putting in oven - looks pretty.
Preheat oven to 325 degrees. Spray a small casserole dish with vegetable oil spray, 7 to 8 inches square or round. Line the pan with 1/2-inch layer of potatoes. Beat eggs. Add dry ingredients and beat well. Blend in remaining ingredients. Batter will be lumpy. Pour in dish and bake 25-30 minutes.
Serves 4.

What 140,000 +/- 113,000???? that seems a bit bigger.

We are simple creatures, no doubt. But the number of genomes does not point to our complexity. Rather, these genomes could be incredibly complex, controlling all sorts of things. They could intermingle, with no clear linear relationship between a single function and a single genome. It would have been easier to decode had there been more, because now it is clear that these genomes are more complex than originally thought.

That's what my mom makes with all the left over genomes. It's always good, but younever know quite how it's going to taste.
Since when is 'surprise' spelled with a z? I was expecting something like a contest for the first group to completely map it, and that it was won immediately, or some such nonsense. A combination of a 'surprise' and a 'prize'.
Otherwise, it's just some horrible spelling.

This kind of news always makes me wary. Did the reporters mean what the author had in mind? Yes, when it comes to genetics I am more suspicious, after all, as a political tool it is too powerful for lunatics to be based on empty air; if you see what I mean.
Does this mean that we're all inbred? I think I'm going to log off and go play my banjo with uncle grandpa for awhile.

Along with the news... comes a suprising observation about the genome: We have substantially fewer genes than expected
This observation was already made a couple of years back when the first draft was published. Note the date on the second link.

Its probably because you just lost around 110,000 genes. It could happen to anyone.

Kidding aside, a lot of the purported "implications" of the finding aren't exactly new. From the article:
That's nothing new, though - scientists have known a long time there's no scientific basis for the concept of "race" as applied to humans. It's a cultural construct.

Damn you scientists.
Begun formally in 1990, the U.S. Human Genome Project is a 13-year effort coordinated by the U.S. Department of Energy and the National Institutes of Health. The project originally was planned to last 15 years, but rapid technological advances have accelerated the expected completion date to 2003. Project goals are to
- identify all the approximate 30,000 genes in human DNA,
- determine the sequences of the 3 billion chemical base pairs
that make up human DNA,
- store this information in databases,
- improve tools for data analysis,
- transfer related technologies to the private sector, and
- address the ethical, legal, and social issues (ELSI) that may
arise from the project.
To help achieve these goals, researchers also are studying the genetic makeup of several nonhuman organisms. These include the common human gut bacterium Escherichia coli, the fruit fly, and the laboratory mouse.A unique aspect of the U.S. Human Genome Project is that it is the first large scientific undertaking to address the ELSI implications that may arise from the project.
Another important feature of the project is the federal government's long-standing dedication to the transfer of technology to the private sector. By licensing technologies to private companies and awarding grants for innovative research, the project is catalyzing the multibillion-dollar U.S. biotechnology industry and fostering the development of new medical applications.
Sequence and Analysis of the human genome working draft was published in February, 2001, in Nature and Science. See an index of these papers and learn more about the insights gained from them.

The point is that the genetic differences behind our racial distinctions are really quite miniscule. The closer you look at them, the harder it is to divide humans into well-defined categories. It is you, I'm afraid, who are holding to a politically-motivated viewpoint that is divorced from reality.
The complexity of organisms is not solely determined by how many genes they have. There are many other factors. One of them is the expression level of different genes. Differentially expressed genes in different cells leads to different cell types, which form tissues, organs, and overall complicated organisms. There are also other ways of conveying information from one generation to the next other than genes. There is an entire epigenome out there -- non-bp modifications to the DNA (e.g., methylation of DNA) and DNA structure (e.g., methylation of Histone-3's at the Lys 4 and 9, v. acetylation at those sites, v. phosphorylation). This relates to imprinting. For interesting reading, do NCBI searches on the following expressions:
Epigenetics
Imprinting
Histone Code
Imprinting Histone Code
Various epigenetic (that is, above the DNA-bp level) states are epigenetically inherited. They often determine chromatin structure, and are involved in a war between maternal and paternal genomes, genetic conflict. And, they contribute to creating a much more cmplicated organism than the number of genes alone would indicate.
Also, it is important to notice that more complex eukaryotes tend to have more transcription factors, zinc-finger proteins, and so on and so forth. The number of regulatory proteins has mushroomed as organisms become more complicated. It is clear that one of the most important things in determining the complexity of organisms is the differential regulation of various genes.

Not to undermine the significance at mapping the genes, but they're the first step. The next is proteins, the building blocks of life described in DNA. They do everything, so naturaly they are being studied closely by biologists and drug companies.
So what if there is fewer genes than expected? It means that the means of describing protiens is not linear. Protiens can fold four different ways, offering many different structural combinations.
The highest level biological system we understand completely is a species of yeast. For a human, the interactions that make the system work are almost unimagineably complex, because there are so many variables. We're just beginning to model them accurately.
Complexity of life is more than just genes.

While I'm certainly not a learned expert, as a new graduate of an Honours Genetics program in Canada, I feel I must point out a few misconceptions found in the story intro.
I let out an audible groan over the 'revelation' that the human genome contains at most 40,000 genes, compared to the original estimate of ~150,000. I was relieved when I noticed that the article linked to dated to 2001. This makes sense, since that discrepancy was first discussed during my courses over two years ago.
The other grain of salt that needs to taken is the idea of a "completed" genome. The human genome is nearly sequenced, however it the annotation of the genome that matters most. To place this into context, the genome of the fruit fly, Drosophila melanogaster, is over 75% annotated. Currently only a small portion of the human genome is annotated, that is to say, the roads are mapped, and the streets (or in this case, genes) are identified and their function characterized. This is one of the most essential tasks still facing biologists today. Without knowing all the potential genes, as well as their function and expression patterns, the human genome is no better a guide than using a globe to navigate the streets of Toronto (or New York, take your pick).
As it has been mentioned before, I won't delve too far into the fact that a given stretch of DNA can code for genes in two different directions, and in three different "frames" per direction. On top of this, the mRNA produced from the DNA can be spliced in numerous ways. A single expanse of DNA can produce countless different proteins - and its proteins, not genes, that carry out all the functions our body needs to survive.
Humans are extremely complex, but as we go about our 'very' important lives, it's humbling to know that on the surface, we do not contain many more genes than some other 'lesser' forms of life on this planet.
"Nokia is not a country, it's the capital of Finland!" -Moderated "Informative". Yeesh.
As far as I know, there is no easy method to distinguish a gene from other parts of DNA sequence. In order to get such an estimate heurictic algorithms that look for characteristic patterns in the sequence are used. Therefore it is hard to say about proofs. These are only estimates, which can be more or less justified. Searching methods are of course tested on other organisms which are better known (e.g. Drosophilia), but we are not really aware of differences and similarities in gene expression of mentioned fruit fly and human.
Besides the number of genes doesn't have to determine anything. It is just the number of different proteins that can be produced in the living cell. What makes an organism really complex is how and when these proteins are produced and this is determined by gene expression which is poorly understood. It can be compared to different methods of encoding. 8 bits are 8 different signals but offer 256 different combinations. If "complexity" of a living organism is exponential to the number of genes, than one gene makes a difference.

Mobo finds you puny earthling, with your 40,000 genes, quite humorous, and worthy of being devoured.
The Kruger Dunning explains most post on
The assumption that each gene codes for one protein is usually false. But, regardless of that, there exists an additional "degree of freedom" that biological organisms can utilize in order to allow themselves to assume as many "states" of gene expression as possible.
The topic of stochastic gene expression is becoming more interesting recently because of further advances in studying single-cell gene expression and the design of genetic regulatory networks.
Because the concentrations of many gene regulatory proteins are so dilute/low, there exists significant fluctuations in the number of molecules that actually regulate the gene's expression. These fluctuations vary from time to time and from cell to cell, producing non-deterministic levels of gene expression. The non-determinism (called stochasticity) can cause some very interesting behavior that leads to numerous potential 'states' of gene expression versus a single, deterministic state.
So, on a very real basis, probability has a lot to do with how certain genes are expressed. Successful biological systems, however, hate random chance unless it's advantageous. These certain genes that utilize the internal noise of a "small" biological system do so because it gives some sort of advantage to them..either coding for numerous possible states with the least number of genes or for allowing the cell to randomly pick between possible states in order to create a heterogeneous cell population.
If you're interested in some scientific articles, try Adam Arkin's paper from 1998, detailing a stochastic simulation of a virus that attacks E. coli cells. The virus randomly selects whether it will replicate itself quickly and burst the cell open or integrate itself into the bacteria's genome and sit dormant. The probability of each event depends on the state of the bacteria at the time of infection. If the bacteria is starved, the virus goes dormant. If it's healthy, the virus goes into replication mode.

All of these observations of having 140,000 genes were made well before ANYTHING had been sequenced, worms, corn, or humans. That was way back in the ancient days of Genetics when geneticists didn't realize how much interaction and recombination there was between genes. Many of the gene estimates came from crude estimates involving antibodies in the early 80s. We knew that we had tens of thousands of antibodies and so they assumed we had oodles of genes to make antibodies. Geneticists realized later that antibodies are coded out about 1/100 as many genes which are have lower than average "quality control standards" than other genes. Antibodies are created from mixing and matching segments of genes.
The more research is published, this phenomenon becomes more and more frequent. So the Central Dogma of Genetics (DNA->RNA->Protien) is slowly breaking down. Genes don't code for just one protein.

Indeed, I don't think the numbers mean anything.
I remember reading somewhere that we are nearly (98.5%) genetically identical to chimps. That measly 1.5% is responsible for the gulf of difference between us and our closest primate. Are there any studies out there just focus on that magical 1.5%?
A race (in humans as in other animals, or even vegetables) is a set of characteristics. Characteristics that evolved mainly as a consequence of environment and culture. If a large number of people share a common set of (physical, anatomical, etc.) characteristics, they can be said to be of the same race. These races (large groups of similar people) were defined during a time when people tended to live their whole lives in one place, and therefore have children with people of the same (or a very similar) group.
As people started to travel across continents (which didn't really happen until some four or five hundred years ago), new "races" were created. Some of these combinations of the "traditional" races became so common that they got their own names (ex., a child of a caucasian and a central or southern african is usually called a mestiço or mulato).
So to answer your question: if a child is born to an interracial couple (meaning two people of clearly identifiable and distinct races), that child will usually inherit characteristics of both races. The child's race? Since you don't say which two races you're talking about, what kind of answer do you expect? It's like asking "if I mix two colours, what colour do I get?"... well, depends on the colours you mix, doesn't it?
As global travel becomes more common, and as cultures influence each other, more and more "races" will be created. Instead of a rainbow with 7 well-defined colours, you'll have a smooth spectrum. The original colours will still be there, but the boundaries between them will be so blurred that it won't be possible to tell where one ends and the other begins. But this doesn't mean that we won't be able to distinguish red from orange, or orange from yellow. It just means that some colours could be classified as either (or we could give them fancy new names and charge extra).
I have no idea what you mean by "the genetic difference between races". A race is a set of many different characteristics. It's a "meta-characteristic". You won't find a gene that determines your "race". But you will probably find a gene (or a small group of genes) that determines the tone of your skin, and another that determines the colour of your hair. And another that determines the colour of your eyes. And another that determines how curly your hair is. And another that determines how long your nose is. And so on. And if a large group of people share a significant amount of features, voilá, you have a race.
A "race" is simply an easy way to refer to a large set of similar elements. Take cars and bikes, for example (two "races" of personal transportation). What distinguishes a car from a motorcycle? The car has four wheels, the motorcycle only has two. But a bicycle also has two wheels, and it's not the same as a motorcycle. And a van has four wheels and it's not a car. To make things even more complicated, a car may not share a single part with another car, but it's still a car, just like the first one. So what defines something as "a car"? A lot of different things, some more important than others. Generally, you know one when you see it. And when something new comes up, it doesn't take long for people to come up with a new name, like "SUV" or "mini-van". Is this wrong, or pointless? I don't think so; it's an easy way to transmit information. If you say something is "a mini-van", people will not automatically know what it looks like or how it drives, but they will know more about it than if you say pretty much any other seven-letter word. Human language (and "mental filing") is based on hints, not complete descriptions. It's not terribly accurate, but it's very fast and, since the receiver has a pretty good processor (brain), you can usually trust him to "decompress" your hint into meaningful data.
So what if a person's basic "racial" features (hair, eye and skin colour, etc.) are determined only be a handful of genes? They're still very visible and (socially) very relevant differences. If you think the discove
In related news, a new study revelead that the users of gnome are between 27,000 and 40,000, contrary to previous estimates of 140,000. Unfortunately, this means that Gnome developers are not as hard-wired as they were once thought to be and new karma-whoring strategies must be adapted.
I think you didn't understand what that sentence meant. A "social construct" does not means that people's races are determined by culture; it means that societies (cultures) determine what consitutes "a race". In other words, "races" are just a simplified (and not necessarily accurate) way to define large sets of characteristics.
But in fact culture does shape races, up to a point. For example, if you have a tribe (or country, or religion, etc.) where green-eyed women are considered "better", they will have a better chance to reproduce and green yees will tend to become more dominant in that culture. Same goes for any other characteristic. Call it "evolution by cultural selection". Cultures change faster than continents drift, though, so the influence of cultural selection (in the long term, at least) is not as big as that of the natural environment.

It's been a popular misconception in the popular media for a long time that traits that are learned are malleable, whereas traits that are innate or genetic are not. This is not the case. The malleability of a trait depends on how it is implemented in the body, not on whether it is inborn or learned.
The simplistic view of the importance of genetic contribution probably stems from the way genetics is taught in school. Your eye color is genetically determined and eye color does not change. However, the reason why eye color does not change is not that it is inherited by genetic inheritance, but because eyes are constructed the way they are.
This is one of the reasons why psychologists worry much less about heritability of traits than they used to. The malleability of any given trait remains an empirical question. Your genes don't know how heritable they are.
For an interesting discussion of heritability and malleability, read Plomin et al's Behavioural Genetics - or the brief version here.

More interestingly than anything else here is the persistence of the idea that humans are in some way 'higher' than other life forms on earth.

More complex, perhaps... but complexity, as is evidenced by, say, American tax law, is not to be confused with supremacy. It figures, though, in a culture that necessitates hierarchy, that most would function under these ideas as if they were universally, empirically, and philosophically true.

Fewer codes means reduced chance for error.
Let's take a couple examples from CS:
Scripting Languages
Procedural Languages/OOP (code reuse)
Crosscutting
Even using these techniques it's common practice to reduce/abstract code until you just can't get any more efficiency out of a system.
Each of these techniques makes the program shorter, contain fewer errors, and therefore better.
Then add in the fact that all of these genes need to be reproduced flawlessly a few million times a day in each creature. If there's an error rate, increasing the code length is just going to increase the expressed errors.
So, let's hear it for smaller gene counts - it's good engineering!

Actually, this is incredibly old. And wrong. You see, they tag new genes by searching for the locations where genes are transcribed (I won't go into the details, but there are deviations in base-pair frequency from normal "random" sequence near and inside genes due to transcriptional regulation and triggering). So once the genome is sequence, it's simple enough to search for the appropriate sequence and say, "Aha! A gene!"
/. should be a bit more current, neh?
The problem is, of course, is that you only see one gene for each transcriptional site. In actuality, our total number of genes may be much larger. This is primarily due to alternative splicing.
pre-mRNA directly off transcription has a number of introns, or integral non-coding sequences. These are eliminated using splicing, cutting out the introns and reconnecting the exons. However, it has been showns that a number of these genes are spliced multiple ways - in particular, it has been shown that different numbers and organizations of exons can be achieved.
Thus, a single "transcriptional location" that has been tagged as a single gene in the original search may code for a variety of mRNAs, and hence varied polypeptides. This has so far been shown (not in humans) to deal particularly for on/off traits - ie, sex determination and the like. It also seems as if alternative splicing of one gene may regulate the alternative splicing of another, producing a cascade effect in cells that can entirely change the way they express genes.
Anyways, even this is years old. Sheesh.

You could patent the idea of modifying a specific gene for certain uses, I suppose....
But IANAL....
There are several aspects to the genome--- Including genetic diagnostics, and gene therapy. These raise significant social and medical questions, and we will see a lot of opposition in the widespread use of many of these technologies.
So, I think that the genome is an important project for our understandinfg of ourselves, but I think the patent issues are too much too soon and many companies may find that during the life of their patents, they will get very little use out of them.

LOL. If you had not posted as AC, I would gladly buy you a beer for pointing out my obvious error in assuming my previous comments would have any application here. I stand corrected.

As human DNA differs somewhat from individual to individual, what does it mean to decipher the human genome? Isn't it a human genome that they're working on?
Peace be with you,

Trade plays a very small role in the mixing of cultures and races. A handful of guys travelling from one country to another, dropping off some spices, taking some swords, and going back home don't cause any significant effects, race- or culture-wise (apart from the effect the trade itself has). Sure, some of them may leave a pregnant woman behind, but that woman's child is likely to marry someone in his or her own society (and culture, and race) and his or her "difference" becomes diluted, and unnoticeable after a couple of generations.
It wasn't until quite recently that significant communities from one country (and race) started moving to, and mixing with, other races and cultures. Not a dozen traders going back and forth - one thousand people immigrating.
Or do you think that the place where you're born determines what you look like, and that's why you have mostly blacks in Africa, mostly whites in Europe, etc.? According to your theory that "races have been mixing since pre-history", shouldn't we all look pretty much the same by now?
Maybe you should read some books about anthropology.

I was under the impression that the patents aren't for the gene sequences themselves, but rather for methods of detecting them... and there's a separate patent involved for each allele for each gene. Effectively, you've "patented the gene" because you're the only one with the right to test for its presence, but I can still copy my genome en masse and distribute it (i.e. reproduce) because I'm not testing for the gene, therefore not violating the patent.

Rui,

According to the theory that I, most anthrologists, most sociologists and many biologists are collectively espousing, there is no such thing as race.
Race is a term that is taxinomically applied to sub-species for living organisms. A sub-species is a geographically, ecologically or temporally separated group that exhibit pronounded morphological differences from the species.
Modern science agrees that all human beings are of the species Homo sapiens and that there are currently no living subspecies. Neanderthalensis may have been a subspecies or may have been a separate species. The jury is still out on this one but leaning, last I heard toward classifying them as another species since it is now believed that they couldn't successfully interbreed with H. sapiens.
One hundred years ago Anthropologists did a good deal of work attempting to define races in order to show that "whites" were superior to "blacks" based on skull size and such. This worked has long since been tossed in the trash. With it, so went the term race when applied to humans.
But before that happened, various 19th century scientists of European decent classified between three and a dozen races. These ideas were taken up by others who had socio-political ideas about how to utilized the concepts of race in society and now we have lots of lay people who believe in race and no (or almost no) scientists who recognize it.
I don't know where you are from but in the US we often see forms collecting government demographic data that will use the term race (perhaps they have dropped it now? But I grew up with that term on forms) and then list five or so races: caucasian, african/black, asian, american indian, asian indian, hispanic. (And hispanic is clearly an ethnicity!!).
Asian indians (people of India) have been reclassified three times in the past 100 years in the US according to race. If I remember correctly, first as caucasian because of the Indo-Aryan "connection", then as black or asian (not sure which) and then finally as their own "race." There was a period of time when it was not clear among those who classified race if Italians were racially caucasian... Do you smell socio-political motivations here?
There is no such thing as race. There IS such a thing as populations and ethnicities. And no, this isn't substituting one term for another. There are thousands of ethnicities but the highest number of races that were enumerated by naturalists in the 19th century were a dozen.
Race is a mote concept. It doesn't exist.
On the other topic, which is a separate but related issue: migrations of people.
Sorry, people have been migrating in both small and large numbers for more than 500 years. Some migrations take 1000+ years and others have been done in less than a generation. Trade routes also open up migration routes.
While not, in my opinion, the best account of migrations, check out "Guns, Germs and Steel" by Jared Diamond. His writing style is a bit pedantic (to me, as a trained anthropologist, to the point of complete annoyance; to my friend, a trained mathematician, the writing style was thought provoking -- YMMV). But he tackles the big picture of how people migrated all over the earth, populated it, and how certain populations managed to either interbreed or wipe out others on many different continents over many many more years then you are talking about, sometimes with surprising speed.
Good day.
I spent all of those years as Anonymous Coward and all I got was this lousy number (204976).
You sound a lot like minister al-Sahhaf. "There is no race, I tell you. We have destryed the race, the race is commiting suicide. The infidels are saying there is a race but they are lying, we will destroy them. Do you see any race here? I don't see any race. There is no race. Good day."
Nuclear physicists can "agree there is no such thing as chemistry" all they like. But it's still a meaningful word that describes a lot of tools and processes that human society uses daily. So "chemistry" is real. Since no-one can prove there is a god, "religion" can also be said to be "meaningless". But clearly it's not. People pray, people make speeches, people read their holy books, so clearly "religion" is also real, and so is god, in a way. And since different groups of people tend to have different characteristics, the concept of "human race" is clearly real too (as are the concepts of "height", "gender", "beauty", "strength", "intelligence", and so on - some more subjective than others, but all very much real).
There are very few things (none, atually) that you can establish as being "the ultimate truth". Cells aren't real, they're just groups of molecules. Molecules are just groups of atoms, atoms are just electrons and protons and neutrons, and so on. But it's not very practical, when I'm describing another person, to say "the superstrings that define the area of this universe's membrane that [...etc....]". It's easier to just say "she's white, with green eyes".
I doubt you can came up with a sentence of less than 6 words that gives more information about what "she" looks like.
As I said, if you have a problem with the word "race", feel free to come up with a different one (you don't like "frex", try "nabo"). As Humpty Dumpty said, "when I use a word, it means just what I choose it to mean, neither more nor less". To me, "race" is simply a way to quickly and broadly define a large group of physical characteristics, that would take too long to describe one by one. It's not 100% accurate, but usually it doesn't need to be. I really couldn't care less about "how many genes define a race" (which is meaningless, anyway), just as I couldn't care less about the chemical composition of marron glacé.
As to the migrations, I think this is pointless. You seem to think that a group of 10 or 20 people (or even 100) moving from one country to another over a generation (say, 20 years) will have a significant impact on "interracial breeding". Which is clearly wrong (see my messages above for why it's wrong, or just try looking at the real world). But hey, you also say "races don't exist" in the first place, so I guess the whole thing is irrelevant.
Maybe then you'd care to explain why - if people have been migrating and interbreeding in huge numbers for tens of thousands of years - the various human races (or "ethnicities", if you prefer) haven't all blended together into a single, worldwide race (or "ethnicity", or "frex", or "nabo", or whatever you want to call it).
