The Genetic Code – What Exactly is it? Every strand of DNA has a chain of base pairs. The base pairs make up a code. This code names different amino acids for building proteins. Three bases together are called a codon and each codon spells out one amino acid. There are 64 possible codon combinations, but only 20 amino acids. The code has many overlaps. Many amino acids together build a specific protein. This is called protein synthesis. This is the genetic code.
