WebbThe start codon marks the site at which translation into protein sequence begins, and the stop codon marks the site at which translation ends.. How do we know which codon codes for which amino acid? Use a Genetic … WebbThere are three amino acids encoded by six different codons: serine, leucine, and arginine. Only two amino acids are specified by a single codon each. One of these is the amino-acid methionine, specified by the codon AUG, which also specifies the start of translation; the other is tryptophan, specified by the codon UGG.
