The coveted gold medal is expected to go under the hammer for up to $3.5 million in a sale at Christie's in New York on December 4.It will be the first time a Nobel Prize has been sold by a living recipient.Watson, now 85, was awarded the medal, for work in the field of physiology or medicine, alongside fellow scientists Francis Crick and Maurice Wilkins in 1962.The scientist's notes for his acceptance speech at the Nobel ceremony in Stockholm, and the manuscript of his Nobel lecture, are also on offer at the auction.Watson and Crick worked together on the structure of DNA at the University of Cambridge's Cavendish Laboratory in the early 1950s.On a par with Newton, Darwin and Einstein, [his] unyielding quest for knowledge led to discoveries that forever altered human historyChristie's auction house"He was the first person I met who I could really talk to," Watson told CNN in 2013. "I'd met people, but they didn't share my conviction that only DNA was important."In 1953, the pair came to the conclusion that DNA was formed by two twisted strands of molecules, like the rungs of a ladder, holding the iconic double helix structure together."All we could say when we got it: It's so beautiful!" Watson said.The discovery, which explained how DNA stores information, and how it is replicated, changed biology forever, and revolutionized medicine."Everything we do since then is more or less based on that structure," Mario Capecchi, professor of genetics and human biology at the University of Utah and a former graduate student of Watson, told CNN last year.Announcing the sale, Christie's auction house said Watson's work was "On a par with Newton, Darwin and Einstein, [his] unyielding quest for knowledge led to discoveries that forever altered human history."Bakudaily.Az
