Vedclass · Answer

(D) The correct matches are as follows:$i$. Cistron: It is a segment of $DNA$ coding for a polypeptide $(c)$.$ii$. Exon: These are coding sequences that appear in mature or processed $mRNA$ $(d)$.$iii$. Intron: These are non-coding sequences (intervening sequences) which are removed during the process of splicing $(b)$.$iv$. Capping: It involves the addition of a methylated guanosine triphosphate $(GTP)$ to the $5'$-end of $hnRNA$ $(a)$.Therefore,the correct matching is $i-c, ii-d, iii-b, iv-a$.

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 $mRNA$.
