Researchers Design DNA With New Shapes and Structures
Jason Koebler writes: The shape of DNA is a double helix, right? That's what we are taught. Well, now the answer is "not always." Researchers at the Massachusetts Institute of Technology have discovered how to program DNA to be shaped like a bowl, or a spiral, or a ring, or other shapes that aren't found in nature.
It's the latest in a string of discoveries about the underlying structure of life and the building blocks by which it's made. Recently, scientists created new nucleotides that do not exist in nature and inserted them into a living organism. And now, this: DNA can look like just about anything and can be assembled into many shapes.

Me fifth element - supreme being. Me protect you.
The next step should be to figure out how to create DNA "tools" to help assemble molecular scale machines!

What do you make of it Johnny?! Well, you can make a hat, a broach, a pterodacty!....
Because that is the problem facing humanity now.
How long until someone creates penis-shaped DNA?
(Personal Open Terminal). in this episode mutant crown royal dna is composted in the lhc. 'we're going to grow something here' was the official statement? viewers are feeling ill frequently... tbc reruns https://www.youtube.com/results?search_query=nazi+zion+experiments sheesh phewww
This should be a given, this is how the body makes proteins. The "recipe" is stored in the DNA, the transcriber runs along the DNA making a copy and then it folds into the protein when the copy is complete. A small mistake in the transcription and it doesn't fold into the right protein or doesn't fold at all. This is why protein research is so hard right now, they don't fully understand what governs how the proteins fold.
This research may give them a leg up on understanding that, very cool that they figured out some of the rules.
It is still double helix. It is the tertiary structure that is being played with, not the helix. Without the double helix, it would be to easy to have errors. In addition, nature enzymes are designed for double helix and the zipper effect.
I prefer the "u" in honour as it seems to be missing these days.
DNA shaped like a spiral is the key.

I'm sorry, but your opinion seems to be wrong.
Let me know whey I can visit ill-concieved dinosaur hybrids in Jurassic Park.
Until then I'm going to stick to spreading my DNA by masturbating into toilet paper.
Obviously because you'll never get the chance to deposit your DNA in a vagina.

With this and designed DNA, Pinky and Brain are just one step ahead.

That's dangerous. Putting DNA in a vagina could lead to pregnancy.
This sounds interesting scientifically, but can it lead to some kind of application that's really interesting, or is this just science for science's sake?
I did and this resulted in rapid loss of gathered funds, loss of a job during divorce proceedings, depression and finally loss of a house. In some cases toilet paper or whatever other place you chose to deposit your sperm is better than vagina as this is owned by foreign parasitic species. At least they are foreign and parasitic when sexual organs are important part of a context in which one operates at the moment. At work I do not look at the boobs and arses so I am safe. This of course causes problems too as I was (many times already) taken to be gay because I did not display behaviours characteristic to heterosexual rapists, we all are. I guess we cannot have everything, can we?
I so want to see them make Mobius DNA!

I give up on debugging. From now on, SIGSEGV is a feature.
There's something like a barrel full of DNA in your mom's vagina on any given day. A lot in her stomach, too.
I think the title is misleading.
It sure looks like they are using the double helix style of DNA and then weaving that into shapes or wound ribbons.
Am I missing something here?

I guess we are back to egg or chicken debate.
The primary structure for double-stranded DNA is most often a double helix. Single stranded will try to form similarly complementary structures to minimize unbalanced charges. However from the primary structure you can get into secondary, tertiary, and quaternary structures that go well beyond that. One really good example is the structure of a chromosome which starts with double-stranded DNA (as a double helix) wrapping around histones to form chromatin. From there it condenses further, eventually reaching the level of a chromosome with several steps along the way.
We also know that DNA can form interesting shapes as single-stranded forms that can bind to a lot of non-nucleic-acid molecules (Aptamers being good examples of these).

GMO's aren't the problem, how we use them is.....now this ?
There's a reason to believe in the complexity of Evolution's tests and trials.
When we start mucking around with building blocks like this let's hope we remember that we don't
really know how this lego set will act once it's built up....really interesting though I must admit.
(GMOs belongs in Labs and Cures, not in crops or Livestock)
End of Line.
This isn't even remotely new. People have been doing DNA origami for years. This article isn't about building anything new, it's about software that can better predict how the DNA will fold given a certain construction method.
DNA origami is mostly novelty, anyways. Most researchers have moved on to using DNA to build structures that actually do useful things, rather than just look pretty.
I think is still too early to celebrate the technique, this are mostly just computer predictions that have not yet been proven in the lab, there are a lot of things in biology that are supposed to happen based in computer simulations that simply don't in a flask. If you have a million compounds and dock them to a single active site in a protein you may get around a thousand that are predicted to work inhibiting that site, when you test them you are lucky if a couple really have some kind of significant inhibition. Here they are talking about predicting a shape using hundreds or even thousands of this interactions in a single molecule, I would expect most of this predictions to result false and even those that get it right will do it only on a few cases out of many trials.
