Scientists Modify Organism With Artificial Amino Acid

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."
