Food Biotechnology

A group of three nucleotides that specifies addition of one of the 20 amino acids during translation of an mRNA into a polypeptide. Strings of codons form genes and strings of genes form chromosomes. (See Initiation codon, Termination codon.)

Susan Allender-Hagedorn and Charles Hagedorn — An Agricultural and Environmental Biotechnology Annotated Dictionary

One of the groups of three consecutive nucleotides in mRNA, which represent the unit of genetic coding by specifying a particular amino acid during the synthesis of polypeptides in a cell. Each codon is recognized by a tRNA carrying a specific amino acid, which is incorporated into a polypeptide chain during protein synthesis. In DNA, any informative triplet of bases, including both coding and control sequences. See: genetic code, start codon, stop codon. Synonym: triplet. See: annex 3.
