Har Khorana Family Tree
Har Khorana - A Lifestory
Har Gobind Khorana was a distinguished IndianAmerican biochemist whose groundbreaking research significantly advanced our understanding of the genetic code. Born in Raipur, Punjab, British India (now part of Pakistan), in 1922, Khorana's early education took place under a tree, reflecting the limited resources available in his village. He pursued higher education at Punjab University in Lahore, earning his bachelor's and master's degrees. He then travelled to England to study at the University of Liverpool, where he obtained his PhD in 1948.
Following postdoctoral work at Cambridge University, Khorana moved to the University of Wisconsin–Madison in 1960, where he embarked on the research that would ultimately earn him the Nobel Prize. His work focused on deciphering the genetic code, the system by which genetic information is encoded in DNA and RNA and used to synthesize proteins. Khorana and his team meticulously synthesized artificial genes with specific, repeating sequences of nucleotides. By observing which amino acids were incorporated into proteins based on these artificial genes, they were able to determine which sequences of nucleotides corresponded to which amino acids.
This monumental achievement, accomplished in collaboration with Marshall Nirenberg and Robert W. Holley, earned them the Nobel Prize in Physiology or Medicine in 1968. Khorana's work was crucial in understanding how genetic information is translated into the proteins that carry out essential functions in living cells. Beyond the Nobel Prize, Khorana continued his research, focusing on the synthesis of functional genes. He successfully synthesized the first artificial gene in 1972, a significant milestone in genetic engineering. He later moved to the Massachusetts Institute of Technology (MIT), where he continued his research until his retirement. Har Gobind Khorana's contributions to molecular biology and genetics are immeasurable, and his legacy continues to inspire scientists worldwide. He passed away in 2011, leaving behind a profound impact on the field of science.
