The genetic code is a set of rules that dictate which combinations of three nucleotides (called codons) in DNA code for each of the 20 amino acids found in proteins. Therefore, three bases code for one amino acid. This is known as the triplet code. A single base or two bases cannot code for an amino acid as a minimum of three bases are required for specificity. Five bases codons do not exist in the genetic code.
