In what year was the structure of DNA published?

Explanation:
The key idea here is when the DNA double-helix structure was first published. In 1953, Watson and Crick published a Nature paper proposing the double-helix model, built on Rosalind Franklin and Maurice Wilkins’ X-ray diffraction data and Chargaff’s base-pairing rules. This model showed two strands running in opposite directions with specific base pairing (A with T, G with C), providing a clear mechanism for accurate replication. That combination of structural insight and the supporting data is why 1953 is the correct year. The other years don’t mark the initial publication of the structure. (For context, the work led to the Nobel Prize recognition in 1962.)
