Amino acids are encoded by the full set of 64 triplet combinations of the four nucleic acids that comprise the backbone of DNA. These triplets (sets of three nucleotides) are called codons and are the genetic alphabet of life. <\/p>\n Isaacs, Jesse Rinehart of Yale,,and the Harvard researchers explored whether they could expand upon nature's handywork by substituting different codons or letters throughout the genome and then reintroducing entirely new letters to create amino acids not found in nature. This work marks the first time that the genetic code has been completely changed across an organism's genome. <\/p>\n <\/p>\n Read the original here: PUBLIC RELEASE DATE: 17-Oct-2013 Contact: Bill Hathaway william.hathaway@yale.edu<\/a> 203-432-1322 Yale University Scientists from Yale and Harvard have recoded the entire genome of an organism and improved a bacterium's ability to resist viruses, a dramatic demonstration of the potential of rewriting an organism's genetic code. \"This is the first time the genetic code has been fundamentally changed,\" said Farren Isaacs, assistant professor of molecular, cellular, and developmental biology at Yale and co-senior author of the research published Oct.
