Explanation
Watson and Crick proposed the double-helical model of DNA in 1953, using evidence including Chargaff's rules and X-ray diffraction data from Rosalind Franklin and Maurice Wilkins. Students may choose Darwin because he is famous for a major biological theory, but Darwin did not determine DNA structure.
