Solution

The correct option is D Gamow
Gamow attempted to solve the problem of how the order of the four different kinds of bases (A,T,G and C) in DNA chains could control the synthesis of proteins from amino acids. Gamow suggested that the twenty of the combinations of four DNA bases taken three at a time corresponded to twenty amino acids used to form proteins.
