At lunch Francis [Crick] winged into the Eagle to tell everyone within hearing distance that we had found the secret of life.
— James Watson
Purported remark made at The Eagle pub (28 Feb 1953), near the Cavendish Laboratory in Cambridge, to celebrate the fact that they, Crick and Watson, had unravelled the structure of DNA. Stated by James Watson in The Double Helix: A Personal Account of the Discovery of the Structure of DNA (1968, 1998), 197. However Francis Crick, in What Mad Pursuit (1990), 77, writes that was “according to Jim,” but “of that I have no recollection.” Nevertheless, some quote collections report this incident with a direct quote as “We have discovered the secret of life!”

It has been found experimentally that the ratio of the amounts of adenine to thymine, and the ratio of guanine to cytosine, are always very close to unity for deoxyribose nucleic acid.

The information reported in this section [about the two different forms, A and B, of DNA] was very kindly reported to us prior to its publication by Drs Wilkins and Franklin. We are most heavily indebted in this respect to the Kings College Group, and we wish to point out that without this data the formation of the picture would have been most unlikely, if not impossible.
[Co-author with Francis Crick]
— James Watson
In 'The Complementary Structure of Deoxyribonucleic Acid', Proceedings of the Royal Society of London, Series A (1954), 223, 82, footnote.

We should first look at the evidence that DNA itself is not the direct template that orders amino acid sequences. Instead, the genetic information of DNA is transferred to another class of molecules which then serve as the protein templates. These intermediate templates are molecules of ribonucleic acid (RNA), large polymeric molecules chemically very similar to DNA. Their relation to DNA and protein is usually summarized by the central dogma, a How scheme for genetic information first proposed some twenty years ago.

We should like to propose instead that the specificity of DNA self replication is accomplished without recourse to specific protein synthesis and that each of our complementary DNA chains serves as a template or mould for the formation onto itself of a new companion chain.

We wish to discuss a structure for the salt of deoxyribose nucleic acid. (D.N.A.). This structure has novel features which are of considerable biological interest. [Co-author with Francis Crick]
— James Watson
From James Watson and Francis Crick, 'Molecular Structure of Nucleic Acids: A Structure for Deoxyribose Nucleic Acid', Nature (25 Apr 1953), 171, No. 4356, 737. (Note: in W.F. Bynum and Roy Porter (eds.), Oxford Dictionary of Scientific Quotations (2005), 226, this quote is listed under Rosalind Elsie Franklin and cited, incorrectly, as from “Rosalind Franklin and R. G. Gosling, 'Molecular Structures of Nucleic Acids: A Structure for Deoxyribose Nucleic Acid', Nature, 1953, 171, 737.” However, the actual Franklin and Gosling article in that issue, is on pp.740-741, and titled 'Molecular Configuration in Sodium Thymonucleate'.)

We wish to put forward a radically different structure for the salt of deoxyribose nucleic acid. This structure has two helical chains each coiled round the same axis (see diagram).

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
