Submission + - Scientists create life using artificial amino acid (bbc.co.uk) 2

IndigoDarkwolf writes: The Beeb reports that biologists Sebastian Greiss and Jason Chin have genetically modified a multicellular organism (Caenorhabditis elegans, a tiny worm) to combine an amino acid not found in nature into a custom-built protein. The protein created by their genetically-modified worm contained a dye which glows when exposed to UV light. While previous work showed that genetic modification could incorporate non-natural amino acids into custom proteins for single-celled organisms, this is the first time an entire animal has been modified.

Scientists create life using artificial amino acid

  • It isn't creating life but modifying it.

    • I'm guessing that they didn't replace the amino acid everywhere the organism uses it, because presumably that would be too big a change for it to live. But even changing a few amino acids in some less important genes is interesting. Was the mutant worm able to reproduce, and did the children also successfully express the mutation?

Yes, we will be going to OSI, Mars, and Pluto, but not necessarily in that order. -- Jeffrey Honig
