DNA - Simple English Wikipedia, the free encyclopedia

WebDNA, short for deoxyribonucleic acid, is the molecule that contains the genetic code of organisms. This includes animals, plants, protists, archaea and bacteria. It is made up of two polynucleotide chains in a double helix. [1] DNA is in each cell in the organism and tells cells what proteins to make. Mostly, these proteins are enzymes.
