Question

Quizplus · Accepted Answer

Rosalind Franklin's X-ray diffraction studies of DNA provided evidence for a helical structure, leading to the conclusion that DNA is a double helix. The contribution of Franklin's work was important in the discovery of the structure of DNA by Watson and Crick. Wilkins also played a role in this discovery, but through his collaboration with Franklin and by sharing her data with Watson and Crick. Kary Mullis, on the other hand, developed the polymerase chain reaction (PCR) technique.
