The biggest role in solving the puzzle of the structure of DNA was played by James Watson and Francis Crick. They are credited with discovering the double helix structure of DNA, which is a fundamental aspect of understanding its function in biological systems.

Here are the steps they took:

1. Gathering Information: Watson and Crick first gathered and interpreted x-ray diffraction data that had been collected by Rosalind Franklin, a chemist who was also studying DNA. This data suggested that DNA had a regular, repeating structure.

2. Model Building: Using this data, Watson and Crick began to build physical models of the DNA molecule. They used metal rods and balls to represent the atoms and bonds between them.

3. Hypothesis Testing: They tested their models against the known chemical properties of DNA and the x-ray diffraction patterns. They made adjustments to their models as needed.

4. Confirmation: Eventually, they built a model that fit all the available data. This model, the double helix, was first proposed by Watson and Crick in 1953.

5. Publication: They published their findings in the scientific journal Nature. Their paper, "Molecular Structure of Nucleic Acids: A Structure for Deoxyribose Nucleic Acid," has since been cited thousands of times and is considered a seminal work in the field of molecular biology.

It's important to note that while Watson and Crick are often credited with the discovery of the double helix, they built upon the work of many other scientists, including Rosalind Franklin and Maurice Wilkins.
