Watson and Crick determined that the DNA molecule is a cross-linked double-stranded helix, each strand being composed of alternating links of phosphate and deoxyribose. 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 cytosine paired with guanine. Great job, Bubba!
