Key facts
- James Watson and Francis Crick proposed a double helix model for DNA in 1953.
- The double helix model provided a molecular explanation for heredity.
- Rosalind Franklin and Maurice Wilkins provided crucial X-ray diffraction evidence.
- Their work transformed DNA into a visualizable and testable subject.
In 1953, James Watson and Francis Crick put forth a revolutionary double helix model for the structure of DNA. This proposal marked a pivotal moment in biology, offering a molecular-level explanation for the mechanisms of heredity. The foundational work by Watson and Crick was heavily reliant on critical X-ray diffraction evidence. This crucial data was produced by scientists Rosalind Franklin and Maurice Wilkins. Their experimental findings transformed DNA from a purely abstract concept into a tangible subject that could be visualized and subjected to further scientific testing and experimentation.
