The career of Har Gobind Khorana is a useful demonstration of how biology actually advances - not in a single leap, but in results that hold.
Har Gobind Khorana was born in 1922. His recorded nationality is Dominion of India.
Twentieth-century science was collaborative, expensive and political: the questions were pursued by teams, and the answers had consequences that reached well past the laboratory.
Twenty questions, eight minutes on the clock, and a percentile measured against everyone who has taken it. No sign-up.
Take the IQ test →Biology progresses by comparison, and the comparisons only become convincing once thousands of cases are in hand.
Like many of his contemporaries, Har Gobind Khorana moved between biology and chemistry without regarding the boundaries as real.
The Dominion of India setting is not incidental. National academies, funding and language decided which findings travelled and which stayed local, in this period as in ours.
The measure that matters is durability. Results that survive re-examination become the floor of a discipline, and it is on that floor that everything afterwards is built.
Death came in 2011, at 89. By then the contribution had passed into the settled body of biology, where it is used without being credited - the surest sign that it was right.
