The triplet codon in genetics is:

Who proposed the 'one gene one enzyme' hypothesis?

Since most amino acids are represented by more than one codon,the genetic code is said to be . . . . . . .

During protein synthesis in an organism,the process stops at a certain point. Select the set of codons from the following that can terminate this process.

Hargobind Khorana received the Nobel Prize for his work on:

$A$: Polypeptide sequences are dictated by $DNA$ and represented by $mRNA$.
$R$: Sequence of amino acids in a polypeptide can be predicted by the exact sequence of nucleotides on the $mRNA$ and template $DNA$.
