Assertion and Reason both are correct and Reason is the correct explanation of Assertion.

Vedclass · Answer

(A) The Assertion is correct because the genetic information stored in $DNA$ determines the sequence of amino acids in a polypeptide chain,and this information is transcribed into $mRNA$ as codons.The Reason is also correct because the genetic code is degenerate and specific; therefore,the sequence of nucleotides in $mRNA$ (which is complementary to the template $DNA$ strand) directly dictates the sequence of amino acids during translation.Since the $mRNA$ sequence is a direct representation of the $DNA$ template and determines the amino acid sequence,the Reason correctly explains the Assertion.

$A$: 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 $DNA$.
