DNA Double Helix Discovery — NEET Biology
📚 Practice ConceptHe met Crick and discovered their common interest in solving the DNA structure. Their first serious effort, was unsatisfactory. Their second effort based upon more experimental evidence and better appreciation of the nucleic acid literature, resulted, early in March 1953, in the proposal of the complementary double-helical configuration.
Watson and Crick’s work: (1) Mendel’s results (1865) predated DNA model (1953). (2) Crick’s Ph.D. (1954) followed DNA model. (3) Their 1953 model proposed complementary double-helix. (4) Crick became F.R.S. in 1959. (5) Their work directly followed 1902 theory without intervening advances. Which statements are correct?
