Read the introduction and the “Right Timing” pages of The structure of DNA: Cooperation and Competition. After reading this, you’ll need to watch the movie Double Helix and respond to the following questions.

1. Describe how the following folk contributed to our current understanding of DNA structure:
   1. Linus Pauling
   2. Erwin Chargaff
   3. Rosalind Franklin and Maurice Wilkins
   4. James Watson and Francis Crick
   5. At least one other person
2. List some pieces of information that were critical to the process that led Watson and Crick to their momentous insight.
3. Rosalind Franklin died in 1958 from ovarian cancer. The Nobel Prize is never awarded posthumously (to people who have already died). In addition, a Nobel Prize is only awarded to a maximum of 3 people at one time. Imagine Franklin had NOT died. Who do you think would have gotten the award in 1962? Why?
4. What did you think of this movie?
