Who built the first accurate model of the DNA as a three-dimensional double-helix strand and was awarded the Nobel Prize in 1962?

• A. Rosalind Franklin
• B. Maurice Wilkins
• C. Watson & Crick
• D. James Watson

Answer: (C)

James Watson and Francis Crick produced the first accurate three-dimensional model of DNA as a double helix, using key evidence from X-ray diffraction work by Rosalind Franklin and Maurice Wilkins. Their DNA model explained how genetic information is stored and copied, linking structure to function. In 1962, Watson, Crick, and Wilkins were awarded the Nobel Prize for discoveries about the molecular structure of nucleic acids and its significance for biology. Franklin contributed crucial data, but she did not receive the Nobel Prize, which is not awarded posthumously.
