Other Scottish Country Dances for this Day
Today's Musings, History & Folklore
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.
In late breaking news, close to the original DNA structure discovery is the recent finding of a twisted knot structure, the i-motif, a new DNA structure within living human cells!
Rosalind's Fancy, devised by Anselm Lingnau, is dedicated to the memory of Rosalind Elsie Franklin (25 July 1920 – 16 April 1958) an English chemist and X-ray crystallographer who made contributions to the understanding of the molecular structures of DNA (deoxyribonucleic acid), RNA (ribonucleic acid), viruses, coal, and graphite.
Franklin is best known for her work on the X-ray diffraction images of DNA while at King's College, London, which led to the discovery of the DNA double helix for which James Watson, Francis Crick and Maurice Wilkins shared the Nobel Prize in Physiology or Medicine in 1962. Watson suggested that Franklin would have ideally been awarded a Nobel Prize in Chemistry, along with Wilkins, but the Nobel Committee does not make posthumous nominations.
This dance contains not only the "double helix" figure (for two sets of two couples), but the "Rose progression" figure as a namesake nod for Rosalind herself.
In molecular biology, the term double helix refers to the structure formed by double-stranded molecules of nucleic acids such as DNA. The term entered popular culture with the publication in 1968 of The Double Helix: A Personal Account of the Discovery of the Structure of DNA, by James Watson.
See below and click on the famous Photograph 51, the nickname given to an X-ray diffraction image of DNA taken by Raymond Gosling in May 1952, working as a PhD student under the supervision of Rosalind Franklin, at King's College London in Sir John Randall's group. It was critical evidence in identifying the structure of DNA.
