Redosled tri nuleotida u molekulu DNK, koji određuje mesto odgovarajuće aminokiseline u molekulu polipeptida pri translaciji mRNK. Za svaku od 20 aminokiselina postoji (najčešće) nekoliko mogućih kodova (triplet baza u DNK) ili odgovarajućih kodona (triplet baza u mRNK).
The three-letter code that translates nucleic acid sequence into protein sequence. The relationships between the nucleotide base-pair triplets of a messenger RNA molecule and the 20 amino acids that are the building blocks of proteins.
