Har Gobind Khorana
The Nobel Prize in Physiology or Medicine 1968

Born: 9 January 1922, Raipur, India

Died: 9 November 2011, Concord, MA, USA

Affiliation at the time of the award: University of Wisconsin, Madison, WI, USA

Prize motivation: "for their interpretation of the genetic code and its function in protein synthesis."

Prize share: 1/3

Work on Electron Diffraction

In the 1950s, it was established that genetic information is transferred from DNA to RNA, to protein. One sequence of three nucleotides in DNA corresponds to a certain amino acid within a protein. How could this genetic code be cracked? After Marshall Nirenberg discovered the first piece of the puzzle, the remainder of the code was gradually revealed in the years that followed. Har Gobind Khorana made important contributions to this field by building different RNA chains with the help of enzymes. Using these enzymes, he was able to produce proteins. The amino acid sequences of these proteins then solved the rest of the puzzle.
