9. Watson and Crick used scientific reasoning, their knowledge of biochemistry, and the research of other scientists to make one of the most important scientific claims of their time: DNA is a double helix with strands running in opposite directions. Between these strands, A pairs with T, and C pairs with G. Complete the table below to explain the evidence that Watson and Crick used to support this claim: DNA is a double helix with strands running in opposite directions. Between these strands, A pairs with T, and C pairs with G. Evidence: (List three pieces of evidence for the claim. Name the scientists who were responsible for each piece.) Reasoning: (In full sentences, explain how each piece of evidence supports the claim.) 6. Watson and Crick first built a triple-helix model of DNA. In this model, the nitrogenous bases were on the outside of the DNA molecule, and the phosphate groups were on the inside. a. At that time, why did it seem reasonable for the bases to be on the outside of the DNA molecule? b. What evidence caused Watson and Crick to revise this model? Give specific examples from the film.
