'''Deoxyribonucleic acid''' ('''DNA''') is a [[nucleic acid]] that contains the [[genetics|genetic]] instructions for the [[developmental biology|biological development]] of a [[Cell (biology)|cellular]] form of [[life]] or a [[virus]]. All known cellular life and some viruses havecontain DNA. In [[eukarote]]s such as animals and plants, the DNA is astored longinside the [[polymercell nucleus]], ofwhile in [[nucleotideprokayote]]s (asuch polynucleotide) that encodes the sequence ofas [[aminobacteria acid residue]]s inand [[proteinarchaea]]s, usingthe DNA is in the cell's [[genetic codecytoplasm]].

DNA is a long [[polymer]] of [[nucleotide]]s (a polynucleotide) that encodes the sequence of [[amino acid residue]]s in [[protein]]s, using the [[genetic code]]. DNA can also encode components of the cell that are made from [[RNA]] such as parts of the [[ribosome]]s.
