      Short for deoxyribonucleic acid. The nucleic acid that is the genetic material determining the makeup of all living cells and many viruses. It consists of two long strands of nucleotides linked together in a structure resembling a ladder twisted into a spiral. In eukaryotic cells, the DNA is contained in the nucleus (where it is bound to proteins known as histones) and in mitochondria and chloroplasts. In the presence of the enzyme DNA polymerase and appropriate nucleotides, DNA can replicate itself. DNA also serves as a template for the synthesis of RNA in the presence of RNA polymerase.
