A Google Doodle is a special, temporary alteration of the logo on Google's homepages. Google honoured Indian-American biochemist and Nobel laureate Har Gobind Khorana, known as the first scientist to chemically synthesise DNA molecules, with a doodle marking his 96th birth anniversary.
Khorana was born in Raipur, which is Kabirwala in present-day Pakistan. He was the youngest of five children.
His father Ganpat Rai Khorana worked as a taxation clerk in the British Indian administration. The Khoranas were the only literate family in the village with nearly 100 people.
From 1952 to 1960, Khorana served as a faculty at the University of British Columbia, where he began his Nobel Prize winning work in the field of biologically interesting phosphate esters and nucleic acids.
In 1966, he became a naturalized citizen of the US and also received the prestigious National Medal of Science award.
In 1968, he bagged the Nobel Prize for Physiology or Medicine along with Marshall W. Nirenberg and Robert W. Holley for his 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.
Khorana died of natural causes in November 2011 in Massachusetts, aged 89. He is survived by his children Julia and Davel.
