Design of the Coins
According to detail published by The Gazette, the obverse will have the usual effigy of HM The Queen with the inscription “· ELIZABETH II · D · G · REG · F · D · 50 PENCE · 2020” and for the reverse a depiction of photograph 51 accompanied by the inscription “ROSALIND FRANKLIN DNA” and “PHOTOGRAPH 51”. The coins shall have a plain edge.
What did Rosalind Franklin discover about DNA?
Franklin is best known for her work on the X-ray diffraction images of DNA, particularly Photo 51, 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.
Why was Rosalind Franklin not awarded the Nobel Prize?
Her data was critical to Crick and Watson’s work. Sadly, Franklin would not have been eligible for the prize as she passed away four years before Watson, Crick, and Wilkins received the prize, and the Nobel is never awarded posthumously.
