Happy DNA Day! In case you have never heard of DNA day, April 25th is the day the scientific world celebrates the anniversary of the formal announcement of the discovery of the structure of DNA, as well as the anniversary of the Human Genome project being completed.
The race was on in the early 1950’s to determine what the actual structure of DNA was. When scientists James Watson and Francis Crick first made their discovery of Deoxyribonucleic Acid being a double helix, it was actually February 28th, 1953.
