Rounding out the story begun in the previous installment, episode 13 of the DNA Papers centers on the publications in which the double helical structure for DNA was proposed, detailed, and its various implications speculated upon. It features four papers, all by Watson and Crick from Cambridge,. Together these papers not only proposed that DNA’s three dimensional structure was a double-stranded helix, but also described the antiparallel and complementary nature of its two component strands and the specific pairing of the component nucleotide bases, namely, the purines, A and G, with the pyrimidines T and C respectively. The papers also discussed the implications of these features for the fundamental functions of DNA.
