DNA. Computer artwork of a DNA molecule wrapped around a human figure. DNA (deoxyribonucleic acid) is the molecule which carries the genetic code. It is found in all living things, and controls growth and development. It comprises two sugar-phosphate strands (blue) joined by cross-linking bases (not seen). Four types of base are found in DNA, and their order on the strands determines an organism's characteristics.
