$A$ and $R$ are both true,but $R$ is not the correct explanation of $A$.

Vedclass · Answer

(B) Assertion $(A)$ is true because $DNA$ acts as a template for the transcription of all three major types of $RNA$ ($mRNA$,$tRNA$,and $rRNA$) in the cell.Reason $(R)$ is also true because $mRNA$ provides the genetic code,$tRNA$ brings amino acids to the ribosome,and $rRNA$ forms the structural and catalytic components of the ribosome,all of which are essential for protein synthesis.However,the reason $(R)$ explains the functional importance of $RNA$ types,not the mechanism of their synthesis by $DNA$. Therefore,$R$ is not the correct explanation of $A$.

Column-$I$	Column-$II$
$i$. Cistron	$a$. Addition of methylated $GTP$ to $5'$-end of $hnRNA$.
$ii$. Exon	$b$. Non-coding sequences which are removed by splicing.
$iii$. Intron	$c$. Segment of $DNA$ coding for a polypeptide.
$iv$. Capping	$d$. Coding sequences which appear in processed $mRNA$.

$A$: All types of $RNA$ are synthesized by $DNA$.
$R$: All three types of $RNA$ are important in protein synthesis.
