Vedclass · Answer

(A) The $RNA$ world hypothesis suggests that $RNA$ was the first genetic material and performed both catalytic and coding functions.Splicing,the removal of introns from pre-$mRNA$,is a complex process that highlights the catalytic capabilities of $RNA$ (ribozymes),which is a hallmark of the $RNA$ world.Introns are considered 'junk' or non-coding sequences in modern eukaryotes,but their presence is widely regarded as a remnant of the ancient $RNA$ world,suggesting that the split-gene arrangement is an ancestral feature.Therefore,both the assertion $(A)$ and the reason $(R)$ are correct,and $R$ provides a valid context for the evolutionary significance of $RNA$ processing.

$A$ - The process of splicing represents the dominance of $RNA$ world.
$R$ - The presence of introns is reminiscent of antiquity.
