Question

Which scientist proved the triplet nature of the genetic code through frame-shift mutation experiments in 1961?

विकल्प

• Francis H. C. Crick

• George Gamow

• Har Gobind Khorana

• Marshall Nirenberg

Answer 1

Francis H. C. Crick experimentally proved that the genetic code is a triplet code through frame-shift mutation experiments in 1961. These experiments involved deleting or inserting nucleotides and observing how protein synthesis was affected, providing empirical evidence for Gamow's earlier hypothesis.
