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