DNA Featured 16 Dec 2003 Image


DNA, conceptual computer artwork. Deoxyribonucleic acid is the molecule that controls the growth, development and functioning of all living things. It comprises a pair of sugar-phosphate strands spiralling around each other in a double helix. The strands are linked by the interactions between bases on each strand.

DNA encodes information as a sequence of base pairs. The strands contain sections called genes, which are recipes for proteins, the main structural and functional components of the body
