Synthetic Genome Drives Bacterial Cell

Dr. Eggman writes "Physorg.com brings us news of a synthetic genome, produced by the J. Craig Venter Institute, being used in an existing bacterial cell for the first time. Using a combination of biological hosts, the technique produces short strings of DNA by machine which are then inserted into yeast to be stitched together via DNA-repair enzymes. The medium sequences are passed into E. coli and back into yeast. After three rounds, a genome of three million base pairs was produced." (More below.) "Specifically, the genome of M. mycoides was synthesized from scratch. This synthetic genome was then inserted into the cells of a bacteria known as Mycoplasm capricolum. The result is a cell, driven by a synthetic genome, producing not the proteins of Mycoplasm capricolum, but of M. mycoides. The institute has far-reaching plans for its synthetic life program, including designing algae that can capture carbon dioxide, make new hydrocarbons for refineries, make new chemicals or food ingredients, and speed up vaccine production." The BBC has coverage of the hybrid cell as well.

      The grandparent post was modded as flamebait, but the religious flame war is in real life. From the parent's article:

      However, with this step forward comes a new set of ethical considerations, say experts. “We need to be critically aware of the profound implications of creating synthetic life,” said Karl Giberson, director of the Forum on Faith and Science at Gordon College in Wenham. “I don’t think this is something to be scared of. I don’t think Mother Nature is being violated in some egregious way. But this is an area of science with important ethical considerations, and religious sensibilities and higher priorities need to be on the table, under discussion.”

      It's a pretty moderate response, but even so, it conflates ethics and religion, implying that the ethical decisions should be based on theology. The grandparent is right - this is going to be a culture war thing.

Let's also say that that egg develops into a regular person. Is that person property? What happens if they have kids? Do they need to pay royalties?

      It can be done, and that means it will be done. The first applications will be medical; synthetic gene therapy could offer cures for many diseases we currently have no way to treat, and only "it's bad 'cause it's got DNA in it!!!" Luddites will object. Yes, there will be harmful side effects, including death, but people with terminal cancer, or parents of children with terrible birth defects, will be willing to take the risk. Once the therapeutic principles are established, we'll inevitably see more frivolous applications. And at that point, whether or not it's "welcomed by society" will be irrelevant -- as long as there are people with the money to pay for it, someone will do it.

      That being said, we're a long way from that point. There's a hell of a lot of difference between building a bacterial genome and modifying a human one at will.

    The genome was produced by machine (from a digital copy of a sequenced genome). Presumably, if somebody wrote a brand new genome, it could be inserted into a living organism by the same procedure.

    I guess we can now start finding out which genes are really necessary for an organism to function...

  9. Did the institute "make" it and is this "life"? by interkin3tic · · Score: 5, Insightful

    I guess we should wait until the actual Science article comes out, but it looks like they basically synthesized an entire bacterial genome, as opposed to the normal way of having a bacteria copy it's own genome with it's own enzymes, and then they put it into a different bacterial strain.

    Is that "making" a cell artificially? They didn't make most of the bacterial cell themselves, the bacteria did that. They didn't design the genome from scratch, they just copied an existing one that nature made and modified it a bit. I'm not sure that constitutes actually making a cell artificially. If you buy a mac at a store, print out the ones and zeros to make windows vista, manually retype them, make a boot disk, and install that on the mac and it worked, that would be an impressive feat, sure, but did you "make a completely new computer?" (Best comparison I could come up with, sorry about that in advance). I don't think this can be considered making life yet.

    Second, is this "life?" Life seems to be impossible to define, but it's pretty certain that "genome was stitched together in a lab and inserted into a dummy cell" is unique to this thing, nothing else we'd call life has that feature. Does that disqualify it as life and make it something else?

    To their credit, Venter doesn't seem to be claiming they made new life, but they are aiming for that eventually, and I'm curious as to what slashdot thinks about when we can actually say we've created artificial life.

      Personally, I would prefer to wait until we produce a novel self-replicating "machine" (biological or otherwise) before we call it artificial life. Synthetic life, however, yes I would qualify this as. At least, in the sense that it is the artificial construction of a known quantity/concept through synthesis between related assets. That is to say, this and its project, like much of genetic engineering, is a cut and paste job. This achievement is the latest in a reduction of the cut and paste; the latest in a process of producing successively more fine grained reassembly jobs towards any of the goals of a the development of a novel mechanism (directed evolution or generative engineering which I like to call "gengineering"), a synthesis of of existing mechanisms in a singular form (recombinant and splicing GM), or imitation of an existing form. We're not to artificial life yet, but somewhere down the row of increasing granularity lies an invisible line which, when crossed, will I be satisfied in calling it such.

      As an aside, I really was conflicted whether to state my opinion here or mod you up to increase the chances of getting more opinions. Ultimately, I decided yours is strong enough to stand on its own. Good luck in getting to 5!
