A letter written by one of the Cambridge scientists who discovered the structure of DNA to his young son has sold for more than five million dollars at auction in New York.

Francis Crick penned the letter to his son Michael in 1953.

In it, he describes the breakthrough and even sketches an outline of the famous double helix structure.

It fetched $5.3 million when it went under the hammer at Christie's.
