उत्तर
- George Gamow suggested that the genetic code should be made up of a combination of three nucleotides.
- He proposed that if 20 amino acids are to be coded by 4 bases, then the code should be made up of three nucleotides. 43 = 64 (42 = 16), which is less than 20. So, the codon was proposed to be a triplet.
