1953–1973 CE · structure, genetic code and recombinant-DNA milestones · Europe · Science
In 1953 Watson and Crick proposed a double-helix model using constraints including Rosalind Franklin and Raymond Gosling’s diffraction work and Chargaff’s base ratios; later teams deciphered the genetic code and developed recombinant-DNA methods.

Why it matters
DNA had been isolated and connected to heredity through earlier work. Watson and Crick’s model explained a double-helical structure using chemical constraints, Chargaff’s ratios and X-ray evidence produced by Franklin and Gosling and interpreted within the King’s College programme. The milestone is structural explanation, not the molecule’s first discovery.
Nobel Prize in Physiology or Medicine 1962 ↗Researchers later established how nucleotide sequences specify proteins and developed recombinant-DNA methods in the 1970s. Those achievements required different experiments, organisms and teams. Extending the range to 1973 avoids compressing modern molecular biology into one model or one laboratory.
National Library of Medicine: Francis Crick papers ↗Franklin’s data circulated without the informed consultation expected today, while the famous prize excluded her after her death because Nobel prizes are not posthumous. That history should not be repaired by inventing sole ownership for anyone; it calls for precise attribution and attention to laboratory power.
