Crick once said that without Watson he probably would not have made the discovery of the double helical structure of DNA on his own. Describe briefly what you think Crick s major contributions were to their joint discovery. What do you think were Watson s unique contributions? Could Watson have made the discovery on his own, without Crick? Provide as much evidence as you can from the assigned readings to back up your answer to this question (whether yes or no). What factors in the discovery of the structure of DNA best explain why it was Watson and Crick who succeeded first, rather than Franklin and Wilkins, or Linus Pauling?
