Nucleotide base matrix. Computer artwork depicting a matrix of nucleotide bases: adenine (A), cytosine (C), guanine (G) and thymine (T). The sequence of these four molecules on a strand of deoxyribonucleic acid (DNA) is known as the genetic code. Groups of three adjacent bases code for amino acids, which are the basic building blocks of proteins. The genetic code is unique for every individual.
