Design details:

In 1953 two scientists discovered the structure of DNA. The true significance of their research was perhaps not fully understood at the time but today DNA is used as a vital tool in many fields of science, including forensics, medicine and genetics. To commemorate the 50th anniversary of what is arguably the most important scientific development of the twentieth century, The Royal Mint issued a new two-pound coin. The reverse design is the work of the sculptor John Mills. It features the double helix spiralling across the face of the coin, highlighting the strands of chromosomes and the familiar letter notations for the four basic building blocks.
