Yes, there really is such a thing as “DNA Day”. See the Wikipedia entry!
Sixty one years ago today, on the 25th April 1953, the journal Nature published a revolutionary paper by Francis Crick and James D Watson. With crucial help from Rosalind Franklin and Maurice Wilkins, they had built a coherent, credible model of the DNA molecule.
In the paper they say:
“We wish to put forward a radically different structure for the salt deoxyribose nucleic acid. This structure has two helical chains coiled around the same axis” …
“It has not escaped our notice that the specific pairing we have postulated immediately suggests a possible copying mechanism for the genetic material”.
This discovery changed the study of life sciences for ever.
