For the first time, scientists have created life from scratch – well, sort of. Craig Venter's team at the J. Craig Venter Institute in Rockville, Maryland, and San Diego, California, has made a bacterial genome from smaller DNA subunits and then transplanted the whole thing into another cell. So what exactly is the science behind the first synthetic cell, and what is its broader significance?


Posted here due to possibility of religious debate.

Interesting, no matter how you look at it.

Definately some interesting stuff.

I imagine there are a myriad of possibilties that this research opens up. Also some definate hazards as well.

Calling it 'creating a synthetic cell' is a bit of a stretch, seeing as they simply injected DNA into an already existing cell.

The creation of a functioning and replicating DNA hybrid is interesting, but far from creating a synthetic cell.

And honestly, it's not that far from what people have been doing for a long time, modifying the DNA of bacterial cells to produce a specific byproduct (fuel, etc) by hybridizing other DNA sequences into it.

they also moved a step closer to proving evolution of single celled organism by having 1 of the 900somethingish generation grow a flagilla.

Yeah, but they built the DNA entirely from scratch. Which is pretty neat. :P

It is neat, but it is also something the group has done before, some two years ago. It's quite interesting, given that the DNA sequenced was in total around 580,000 BP. Thankfully, it was a bacterial genome, so there was no worry about structural DNA for coiling.

The papers were neat, and I've read them- I just get ticked off about 'public science' reporting that portrays developments as something completely different than what they are in the context of the groups actual work.
