Step 1: Recall the scientists who are credited with determining the structure of DNA.
The structure of DNA was discovered by James Watson and Francis Crick in 1953. They were not working alone, but their collaboration and interpretation of Rosalind Franklin's data significantly contributed to understanding the double helix structure of DNA.
Step 2: Explain the contributions of each scientist.
- James Watson: He was a molecular biologist and geneticist who, together with Francis Crick, proposed the double helix model of DNA. Watson's role involved bringing together various pieces of information and constructing the double helix model. - Francis Crick: He was a British molecular biologist, physicist, and neuroscientist. Crick, along with James Watson, developed the double helix model of DNA. Crick had a strong background in physics and mathematics, which helped in understanding the molecular structure of DNA.
Final Answer
James Watson and Francis Crick are credited with establishing the structure of DNA. However, it is important to note that their discovery relied heavily on the work of Rosalind Franklin, who obtained critical data on DNA's structure through her X-ray diffraction images. Unfortunately, Franklin's contribution was not fully recognized during her lifetime.
