DNA molecule. Computer artwork of the structure of deoxyribonucleic acid (DNA). DNA is composed of two sugar-phosphate strands twisted into a double helix (silver). Between the strands are nucleotide bases (red, blue, green and yellow). There are four different bases: guanine, cytosine, thymine and adenine. DNA contains sections called genes, which encode the body's genetic information.
