'''Deoxyribonucleic acid''' (DNA) is an [[organic compound|organic]] [[chemical compound]] made up of [[molecule]]s shaped like a [[double helix]], a continuously twisted ladder. The individual monomeric building blocks of DNA (and other nucleic acids) are [[nucleotides]], which themselves consist of three principle moieties: A nitrogenous base, a sugar, and a phosphate group. 

DNA carries the [[gene|genet]]ic coding for the [[protein]]s that form the bodies of living [[organism]]s. All organisms contain DNA, and the DNA of a sexually reproducing organism is a mix of its parents' DNA.
