Question 1

True or false: Watson and Crick won the Nobel Prize for discovering DNA's structure in 1962, along with Rosalind Franklin.

Accepted Answer

False. The Nobel was awarded to Watson, Crick, and Wilkins; Franklin had died in 1958 and the prize is not given posthumously.

Question 2

True or false: Watson and Crick discovered DNA's structure entirely through their own lab experiments.

Accepted Answer

False. They built models using others' data, especially Rosalind Franklin's X-ray images, without conducting original experiments themselves.

Question 3

True or false: Chargaff's rules—equal A=T and G=C—were critical for Watson and Crick's base-pairing model.

Accepted Answer

True. Erwin Chargaff's discovery that adenine equals thymine and guanine equals cytosine directly hinted at complementary base pairing.

Question 4

True or false: Linus Pauling, the famous chemist, also raced to solve DNA's structure but proposed an incorrect triple helix.

Accepted Answer

True. Pauling published a flawed three-stranded DNA model in early 1953, which spurred Watson and Crick to accelerate their own work.

Question 5

True or false: Rosalind Franklin's X-ray crystallography image was shown to Watson without her permission.

Accepted Answer

True. Franklin's Photo 51 was shown to Watson by Maurice Wilkins, sparking the double helix insight, without her knowledge or consent.

Question 6

True or false: The 1953 paper announcing DNA's structure was over 20 pages long with detailed data.

Accepted Answer

False. Watson and Crick's famous Nature paper was just one page, with a simple diagram and only 900 words.

Question 7

True or false: The double helix model was instantly accepted by the scientific community without any skepticism.

Accepted Answer

False. Many scientists were initially skeptical, and it took years of additional evidence, including from Franklin's later work, for full acceptance.

Question 8

True or false: DNA's structure was actually discovered a year earlier by a different team in England but went unpublished.

Accepted Answer

False. No such discovery occurred; this is a common conspiracy-like myth. The credit remains with Watson, Crick, and Franklin's data.
