Vedclass · Answer

(A) The genetic code is a triplet,meaning three nucleotides code for one amino acid. Frame shift mutations occur due to the insertion or deletion of one or two nucleotides in a $DNA$ sequence. This shifts the entire reading frame of the mRNA,resulting in the translation of completely different amino acids from the point of mutation onwards. This confirms that the genetic code is read in non-overlapping triplets. Therefore,both the Assertion and the Reason are correct,and the Reason explains why frame shift mutations confirm the triplet nature of the genetic code.

$A$: Triplet genetic code can be confirmed by frame shift mutations.
$R$: Frame shifting involves the change in protein product coded by triplet codons.
