Science glossary film: DNA

Deoxyribonucleic acid, the molecule that stores and passes on genetic information that determines how an organism develops and functions. Its double helix structure was published in 1953 by Francis Crick and James Watson. It is a polymer of simpler blocks called nucleotides, which are arranged in pairs in the double helix. It encodes proteins, and can replicate itself.
