Answer: 1. George Gamow

Key idea: The triplet nature of the genetic code was first theorised by the physicist George Gamow.

Since 20 amino acids must be coded by 4 bases, he argued that 3-base combinations (64) are needed. Crick and colleagues later gave experimental support. Monod and Stahl did not propose this. Option 1.
