3. How was DNA's shape discovered? Give me the name of three scientists who played a role in this discovery? (Hint: I'm looking for the names of two men and one woman).
the shape of DNA  was discovered by first x-ray picture, which led to the discovery of its molecular structure. it was created by Rosalind Franklin using a technique called X-ray crystallography, it revealed the helical shape of the DNA molecule. This fundamental discovery was credited by James Watson, Francis Crick and Roselind Franklin who played a large role in the reasearch.
