DNA

Short for deoxyribonucleic acid. DNA is a macromolecule made up of individual units called nucleotides, and is found in all living cells and some viruses. The DNA molecule exists as a complex of two chains in an intertwined double helix. It is the carrier of genetic information that is passed on from generation to generation by replication of the DNA molecule.
