Some people celebrate DNA Day today to commemorates the anniversary of the publication of Watson and Crick’s 1953 article on the structure of DNA.
1935
The first round-the-world telephone call is made when Walter S. Gifford, president of the AT&T Company, talks with T.G.

1939

1953
The journal Nature publishes the one page article Molecular structure of nucleic acids: a structure for deoxyribose nucleic acid written by Francis Crick and James D. Watson. In it, Crick and Watson reveal the double helix structure of DNA and explains how DNA transmits hereditary information between cells and generations. Their work will earn them a Nobel Prize in 1962.
“This structure has two helical chains each coiled around the same axis… Both chains follow right-handed helices… The novel feature of the structure is the manner in which the two chains are held together by purine and pyrimidine bases… They are joined together in pairs, a single base from one chain being hydrogen-bonded to a single base from the other chain, so that the two lie side by side with identical z-co-ordinates.”
1961
Robert Noyce of Fairchild Semiconductor is granted a patent for a “Semiconductor Device-and-Lead Structure,” the integrated circuit, even as it considered the application of Jack Kilby. (US No. 830,507) The patent will precipitate a prolonged controversy between Noyce and Kilby over the rights to the patent. Kilby had recorded his initial ideas concerning the integrated circuit in July 1958, a half year before Noyce, but Noyce had solved most of the practical problems that Kilby had not. Noyce’s chip was constructed of silicon, while Kilby’s chip was made of germanium. Integrated circuits will eventually replace transistors in computers, allowing the machines to be manufactured in increasingly smaller sizes.
