- See Termination codon.
Susan Allender-Hagedorn and Charles Hagedorn - Cite This Source - This Definition - A set of three nucleotides for which there is no corresponding tRNA molecule to insert an amino acid into the polypeptide chain. Protein synthesis is hence terminated and the completed polypeptide released from the ribosome. Three stop codons are known: UAA (ochre), UAG (amber) and UGA (opal). Synonyms: chain terminator; nonsense codon, termination codon.
