Biology 1953 in science

25 april 1953: dna double helix first formally described.



april 25 – francis crick , james d. watson of u.k. medical research council s unit research on molecular structure of biological systems @ cavendish laboratory in university of cambridge publish molecular structure of nucleic acids: structure deoxyribose nucleic acid in british journal nature. work ranked 1 of dramatic biological discoveries of 20th century, because of structural beauty , functional logic of dna double helix. in 1962, share nobel prize in medicine maurice wilkins, publishes x-ray crystallography results dna in same issue of nature in 1953. third related article published @ same time rosalind franklin , raymond gosling, on molecular configuration in sodium thymonucleate .
