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?
