Chapter 25: Molecular Basis of Inheritance
... DNA specifies the synthesis of proteins because it contains a triplet code: every three bases stand for one amino acid. Each three-letter unit of an mRNA molecule is called a codon. Most amino acids have more than one codon; there are 20 amino acids with a possible 64 different triplets. The code is ...
