Remembering him, Banerjee tweeted: "Remembering Nobel laureate scientist Har Gobind Khorana on his birth anniversary".

Khorana began by studying at a school in his village which was under a tree, and showed a flair for science from a young age. He was the fifth child who was born to the Hindu family in Raipur in 1922 where 100 villagers of Punjab region has now become Pakistani.

Alumni of University of Liverpool, University of Cambridge and University of Punjab, he dedicated his life to education, science and research. He spent post-doctorate year at a university in Zurich to work with Professor Vladimir Prelog for one year. "Nirenberg and Khorana cracked the genetic code".

After a few years, Har Gobind went to work in a university in Vancouver, Canada where he initiated his DNA research. During his time there he was offered "all the freedom in the world" to do his own research, according to Gordon M. Shrum, a Canadian scientist in British Columbia.

Explains Encyclopedia.com, "In addition to developing methods for investigating the structure of the nucleic acids, Khorana introduced numerous techniques that allowed scientists to decipher the genetic code and show how ribonucleic acid (RNA ) can specify the structure of proteins". He became a US citizen in 1966, just two years before his Nobel. In 1968, he and two other researchers at the University of Wisconsin - Madison earned the Nobel Prize in Physiology or Medicine.

-But this was not his only accolade. In 1970, Khorana joined the faculty at the Massachusetts Institute of Technology as the Alfred P. Sloan professor of biology and chemistry, the position he held until he died on November 9, 2011 at age 89. He joined the faculty of the Massachusetts Institute of Technology in 1970, where he would remain until his retirement in 2007. He is survived by his children Julia and Davel.
