Franklin's approach to the DNA problem was painstaking and methodical. She clearly eschewed guesswork. Watson and Crick, on the other hand, did no labor intensive experiments, ventured many guesses about the DNA structure based upon the results of other scientists, and finally triumphed because this informed speculation allowed them to build a model that uniquely conformed to all the known properties of the molecule. Is there anything inherently unethical or of questionable values in the less conventional approach of Watson and Crick?
