A memorial to DNA pioneer Francis Crick has been unveiled at his former college at the University of Cambridge. <\/p>\n
Attending the ceremony at Gonville and Caius was Dr James Watson, the man who shared the 1962 Nobel Prize with Crick for revealing the structure of DNA. <\/p>\n
The engraved stonework, which depicts the double-helix structure of DNA, was unveiled exactly 60 years after the pair's seminal paper was published. <\/p>\n
Their discovery has been hailed as one of the greatest in scientific history. <\/p>\n
Crick's and Watson's groundbreaking work was published in the journal Nature on 25 April 1953. <\/p>\n
Before the structure of DNA was unscrambled no-one had a clear idea how genetic replication - one of the cornerstones of life - worked. <\/p>\n
At the unveiling, in front of friends, colleagues and family, Dr Watson paid glowing tribute to his colleague, who died in 2004. <\/p>\n
The 85-year-old American, who went on to direct the US arm of the Human Genome Project from 1988 to 1992, said: \"Francis was the brightest person I ever interacted with. <\/p>\n
\"I met the great physicist [Richard] Feynman but I didn't understand what he was doing, so it didn't mean anything. Francis I could talk to. <\/p>\n
