Har Gobind Khorana's interest in science began as a young boy under a tree in a small Indian village and lead to helping to decipher the genetic code. Dr. Khorana got hold of a degree in Punjab University in Lahore and resided in British India till 1945 then he moved to England for his higher studies in the Ph.D programme at the University of Liverpool.

The researcher shared the 1968 Nobel Prize for Physiology or Medicine with Marshall W. Nirenberg and Robert W. Holley for research that showed how the order of nucleotides in nucleic acids, which carry the genetic code of the cell, control the cell's synthesis of proteins.

The trio discovered that the order of nucleotides in our DNA determines which amino acids are built. These amino acids form proteins. "Fewer than five years later, Dr. Khorana made a second scientific breakthrough when he constructed the first synthetic gene", Google wrote.

In 1970, shortly after he left Madison to join the faculty of the Massachusetts Institute of Technology, Khorana and colleagues announced that they had synthesised two genes crucial to protein-building work.

Dr Khorana went to America to become its naturalized citizen and received the National Medal of Science.

In 1976, they completed the synthesis of the first fully functional manmade gene in a living cell. According to Al-Jazeera, "Khorana died on November 9, 2011".

Khorana is known as a scientist who revolutionised biochemistry with his pioneering work in DNA chemistry.

Khorana lived in many countries throughout his life. He worked under Professor Vladimir Prelog in Zurich for one year and continued his reserch.
