Final answer:
The false statement about the discovery of DNA structure by Watson and Crick is c. Rosalind Franklin, Watson and Crick used X-ray diffraction methods to demonstrate the helical nature of DNA, while Rosalind Franklin formulated the double stranded structural model of DNA.
Step-by-step explanation:
James Watson and Francis Crick proposed the structure of DNA as a double helix made up of two side-by-side polynucleotide chains. Their model was based on key pieces of information from other researchers such as Chargaff's rules and Rosalind Franklin's X-ray diffraction data. The false statement about the discovery of DNA structure by Watson and Crick is c. Rosalind Franklin, Watson and Crick used X-ray diffraction methods to demonstrate the helical nature of DNA, while Rosalind Franklin formulated the double stranded structural model of DNA.
The false statement about the discovery of DNA structure by Watson and Crick is that Rosalind Franklin formulated the double stranded structural model of DNA. In truth, it was James Watson and Francis Crick who proposed the double helix model. Franklin's critical contribution was the X-ray diffraction data that helped to shape Watson and Crick's understanding of DNA's helical structure. Furthermore, while Watson, Crick, and Maurice Wilkins were recognized with the Nobel Prize in Physiology or Medicine in 1962 for their contributions, Franklin had passed away by then and did not receive the same honor due to Nobel's rules against posthumous awards.
