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

DNA contains genes that code for proteins by first being transcribed into RNA. All organisms contain DNA, except for a few viruses. Offspring of sexually producing organisms contain DNA from both parents.
