Question

Who proposed that the genetic code for amino acids should be made up of three nucleotides?

Options

• George Gamow

• Francis Crick

• Jacque Monod

• Franklin Stahl

Answer 1

George Gamow

Explanation:

The idea that a triplet code a group of three nucleotide bases could code for a single amino acid was first put out by George Gamow. He theorised that combinations of four bases in triplets (4³ = 64 possible codons) were sufficient to encode the 20 amino acids, laying the groundwork for deciphering the genetic code.
