The researchers began to build artificial amino acids in the laboratory--just to see what cells would do with new construction material, and where the exploration would lead.
Previously, the Schultz lab tricked bacteria and yeast cells into translating a naturally occurring three-letter nonsense codon--one that normally has no associated amino acid--within the cells' genomes into one of several artificial amino acids (SN: 8/16/03, p.
An "expanded genetic code" created by the scientists overrides the genetic code of the cells and instructing them to use the artificial amino acids in the construction of proteins.
