Watson-Crick helix


helix

 [he´liks] (pl. he´lices, helixes) (Gr.) 1. a winding structure; see also coil and spiral.2. the superior and posterior free margin of the pinna of the ear.α-helix (alpha helix) the complex structural arrangement of parts of protein molecules in which a single polypeptide chain forms a right-handed helix.double helix (Watson-Crick helix) the structure of deoxyribonucleic acid (DNA), consisting of two coiled chains, each of which contains information completely specifying the other chain.

Wat·son-Crick he·lix

(waht'sŏn crik), the helical structure assumed by two strands of deoxyribonucleic acid, held together throughout their length by hydrogen bonds between bases on opposite strands, referred to as Watson-Crick base pairing. See: base pair. Synonym(s): DNA helix, double helix, twin helix [James Dewey Watson, Francis H. C. Crick]
