The genetic code is read in groups of three letters called codons, with each codon corresponding to a specific amino acid. The first two letters of the codon are most important for determining which amino acid is being inserted into the growing protein chain. The third letter is less important and can often be interchangeable, resulting in a different but chemically similar amino acid being incorporated. Therefore, choice B (the first two letters) is the most important for the translation of many amino acids.
