Watson is a U.S. molecular biologist, geneticist and zoologist, best known as one of the co-discoverers of the structure of DNA in 1953 with Francis Crick. In 1998, the Modern Library placed The Double Helix at number 7 on its list of the 100 best nonfiction books of the 20th century.
In 1953 James Watson and Francis Crick proposed the double-helix structure for the molecule, and by 1966 the genetic code (i.e. which amino acids were coded for by which sequences of DNA bases, and what the remaining codons meant,) had been completely worked out.s a result, Watson and Crick are largely recognized as discovering the structure of DNA for the first time, but it was really Watson, Crick and Franklin (among other, less influential, work by other scientists).
