Watson–Crick model noun
: a model of DNA structure in which the molecule is a cross-linked double-stranded helix, each strand is composed of alternating links of phosphate and deoxyribose, and the strands are cross-linked by pairs of purine and pyrimidine bases projecting inward from the deoxyribose sugars and joined by hydrogen bonds with adenine paired with thymine and with cytosine paired with guanine—compare double helix
