Expanding and reprogramming the genetic code Nature

An expanded genetic code is an artificially modified genetic code in which one or more specific codons have been re-allocated to encode an amino acid that is not among the 22 common naturally-encoded proteinogenic amino acids. The key prerequisites to expand the genetic code are: • the non-standard amino acid to encode, WebGenetic Code Expansion (GCE) technology. GCE technology refers to the use of a cell line or organism that contains the addition of a specially engineered “orthogonal” tRNA/RS pair along with a repurposed codon that together allow the encoding of an amino acid that is not among the 20 canonical (i.e. standard) amino acids. dark chocolate chess pieWebSep 29, 2024 · This triplet codon system in principle can encode 64 different amino acids (4 3 )—yet typically only 20 amino acids are used in most organisms.
