Har Khorana is offered a job position at British Columbia University from Dr. Gordon M. Shrum. In these years he works with a group of researchers in the field of biologically interesting phosphate esters and nucleic acids.

Har Khorana receives one third of the Nobel Prize in Physiology or Medicine along with Robert W. Holley and Marshall W. Nirenberg "for their interpretation of the genetic code and its function in protein synthesis".

Har Khorana enters Punjab University, where he earns his bachelor.

Har Khorana attends D.A.V. High School. Here Ratan Lal, one of his teachers, influences him greatly.

Har Khorana dies in Concord, Massachusetts from natural causes at the age of 89.

Khorana enters Cambridge University after a brief period spent in India. He receives a fellowship to work with Dr. G. W. Kenner and Professor A. R. Todd. This stay develops Khorana’s interest in both proteins and nucleic acids.

Har Khorana leaves India to earn his Ph.D. under Roger J. S. Beer at the University of Liverpool.

Har Khorana enters the Institute for Enzyme Research at the University of Wisconsin.

Har Khorana becomes the Alfred Sloan Professor of Biology and Chemistry at the Massachusetts Institute of Technology where he works until retiring in 2007. In 1976, Khorana’s team creates a second gene, which is capable of functioning in a living cell. Such work helps scientists in understanding gene action and it can be useful to make valuable proteins and, perhaps, to cure human hereditary diseases.

Har Khorana enters Eidgenössische Technische Hochschule (ETH) in Zurich for a postdoctoral year with Professor Vladimir Prelog, a fundamental figure in Khorana's formation.

Har Khorana is born in Raipur, a village in Punjab, now part of eastern Pakistan. He is one of the six children of a British Indian tax clerk and his wife.

Har Khorana earns his M. Sc. Degree under Mahan Singh.

Har Khorana confirms Nirenberg's finding that the position of the four types of nucleotides on the DNA molecule determines the chemical composition and function of new cells; then he studies the nucleotide combinations that form specific amino acids and he succeeds in synthesizing each of the 64 nucleotide triplets that make up the genetic code. In 1970 then he announces the synthesis of the first artificial gene.
