10| DNA Structure | Data available to Watson and Crick | Bruce Fraser and Linus Pauling DNA Model

Pauling proposed a triple helix structure with the bases on the outside, but James Watson and Francis Crick ultimately disproved his idea with their famous double helix model.

Fraser’s model of DNA, completed very quickly, was a simple structure that had what would turn out to be all main features correct except for the number of chains. It had a helical shape, phosphates on the outside, and bases stacked like a pile of pennies, separated by the 3.4 Å distance worked out by Astbury.
