Why did Watson and Crick succeed when Pauling failed?

Watson and Crick succeeded in determining the structure of DNA because they were able to use X-ray diffraction data from Rosalind Franklin and apply it to their model-building techniques. Pauling, on the other hand, incorrectly proposed a triple-helical structure for DNA due to the data available to him at the time. Watson and Crick's collaboration and access to critical data were key factors in their success.
