DNA Day DNA Day National DNA Day is a holiday celebrated on April 25. It commemorates the day in 1953 when James Watson, Francis Crick, Maurice Wilkins, Rosalind Franklin and colleagues published papers in the journal Nature on the structure of DNA. Furthermore, on that day in 2003 it was declared that the Human Genome Project was very close to complete, and "the remaining tiny gaps [we]re considered too costly to fill." In the United States, DNA Day was first celebrated on April 25, 2003 by proclamation of both the Senate and the House of Representatives. However, they only declared a one-time
Non-helical models of DNA structure image with Raymond Gosling, Maurice Wilkins, Alexander Stokes, and Herbert Wilson, as well as base-pairing chemical and biochemical information by Erwin Chargaff. Wilkins and colleagues also reported on X-ray patterns of the state of "in vivo" B-DNA in partially oriented salmon sperm heads. Crick, Wilkins, and Watson each received one-third of the 1962 Nobel Prize in Physiology or Medicine for their contributions to this discovery. Franklin, whose breakthrough X-ray diffraction data was used to formulate the DNA structure, died in 1958, and thus was ineligible to be nominated for a Nobel Prize. In 1963, John Cairns published autoradiographs of the
