Who were the scientists that contributed to the discovery of the DNA double helix structure?

• A. Darwin, Mendel
• B. Franklin, Watson, and Crick.
• C. Pasteur and Curie.
• D. Mendeleev and Franklin.

Answer: (B)

Understanding who contributed to revealing the DNA double-helix structure means recognizing how experimental data and a thoughtful model came together. Rosalind Franklin produced crucial X-ray diffraction images that showed DNA’s helical shape and helped define its dimensions. James Watson and Francis Crick then used that evidence to build the first accurate model of DNA as a right-handed double helix with complementary base pairing. Because their model directly reflects Franklin’s data and the structural insights, Franklin, Watson, and Crick are the names most closely tied to discovering the DNA double-helix structure. The other pairs listed come from different areas of biology or chemistry, not from unveiling DNA’s shape.
