39. The Genetic Code The codon AUG specifies the amino acid Methionine which always begins a protein molecule. There is no amino acid associated with the codons UAA, UAG, and UGA. These codons always end a protein molecule. Note: there are 6 codons which specify Leucine and Serine, only a single codon for Methionine and Tryptophan. All the other amino acids have at least 2 codons which specify them.
