To connect the scientists to their contributions to our understanding of DNA: 1. Erwin Chargaff: - Found that the amount of adenine equals the amount of thymine, and the amount of guanine equals the amount of cytosine. - Contribution: Discovered the base pairing rules in DNA. 2. Rosalind Franklin: - Took x-ray images of the DNA molecule. - Contribution: Provided crucial data through her X-ray diffraction images, which aided in determining the structure of DNA. 3. Maurice Wilkins: - Contribution: Worked with Rosalind Franklin and provided support for the DNA structure through her X-ray images. 4. James Watson and Francis Crick: - Proposed a double-helix model of DNA. - Contribution: Developed the double-helix model of DNA, incorporating Chargaff's base pairing rules and Franklin's X-ray data to elucidate the structure of DNA.
