Answer 1

Watson and Crick used Rosalind Franklin's photo to determine that DNA was a double helix.

Step-by-step explanation:

Watson and Crick used Rosalind Franklin's photo to determine that DNA was a double helix. Franklin's photo, known as Photo 51, provided crucial evidence of the helical structure of DNA. Watson and Crick used this information, along with their own data and insights, to develop the double helix model of DNA.
