CHEM 161 "The Double Helix” Worksheet Reading (file:///C:/Users/Kayla/Desktop/Watson_The_Double_Helix.pdf) With whom was Francis Crick talking when he revealed he did not remember the structure of the four bases of DNA? What was that person's own contribution to understanding DNA structure? Watson and Crick hypothesized an early DNA structure model that they showed to Wilkins and Franklin. What were they major structural features of that model, and what was the evidence that made that model less attractive? The structure of DNA was...
