Concept information

Preferred term



  • [Hendersons] deoxyribonucleic acid, a very large linear molecule which acts as the store of genetic information in all cells. It contains carbon, oxygen, hydrogen, nitrogen and phosphorus. A DNA molecule is composed of two chains of covalently linked deoxyribonucleotide subunits, and a single molecule may be millions of nucleotides in length. The two chains are wound round each other to form the Watson–Crick righthanded “double helix”. The four types of deoxyribonucleotide subunit in DNA contain the bases adenine (A), thymine (T), cytosine (C) and guanine (G) respectively. Each chain is composed of nucleotides
