Har Gobind Khorana (January 9, 1922 – November 9, 2011) was an Indian American biochemist. He 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 relationship Khorana and his colleagues discovered is NOT a chemical affinity based on law-like mechanical necessity. The genetic code is just that — a code. Blind natural forces do not create codes. What is the sole known origin of codes? Intelligent agents of course.
