Ximena Newman · Answer 1

The correct answer is: E) did all of these things.

Explanation:

James Watson and Francis Crick were two biologists that worked together in Cambridge to study the structure of the DNA. Two other important biologists in these discoveries were Maurice Wilkins and Rosalind Franklin.

In 1953, Watson and Crick published a paper with their discovery: the DNA molecule has the shape of a double helix, which also explained how the process of DNA replication worked.

Fresier · Answer 2

Answer: d

Explanation:Watson and Crick proposed the structure/concept of the DNA double helix, explaining the base complementarity held by hydrogen bond. Adenine base pairing with thymine and guanine pairing with cytosine. The model also successfully explains then diameter of the double helix, number of base pairs within turns among others.
