DNA molecule and face. Computer artwork of a section of a molecule of DNA (deoxyribonucleic acid) and a human face in profile. DNA is composed of two strands twisted into a double helix. Each strand consists of a sugar-phosphate backbone (blue) attached to nucleotide bases (between backbones). There are four different bases: guanine, cytosine, thymine and adenine. DNA contains sections called genes, which encode the body's genetic information.
