Watson and Crick's DNA Structure Discovery — NEET Biology
📚 Practice ConceptA critical influence in Crick's career was his friendship with J. D. Watson, then a young man of 23, leading in 1953 to the proposal of the double-helical structure for DNA and the replication scheme. Crick was made an F.R.S. in 1959.
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?
