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