Vedclass · Answer

(B) The split gene arrangement (presence of introns and exons) is considered an ancient feature of the genome because it is found in most eukaryotes,suggesting it was present early in evolutionary history.Assertion $(A)$ is correct.$	ext{hnRNA}$ (heterogeneous nuclear $RNA$) undergoes processing steps including splicing (removal of introns),capping (addition of methyl guanosine triphosphate at the $5'$ end),and tailing (addition of poly-$A$ tail at the $3'$ end) to become functional mRNA.Reason $(R)$ is also a correct statement regarding $	ext{hnRNA}$ processing.However,the reason provided does not explain why the split gene arrangement is considered an ancient feature.Therefore,both statements are correct,but $(R)$ is not the correct explanation of $(A)$.

Column $I$	Column $II$
$A$. Griffith	$i$. Lac operon
$B$. Jacob and Monod	$ii$. $DNA$ is the genetic material
$C$. Meselson and Stahl	$iii$. Transforming principle
$D$. Hershey and Chase	$iv$. $DNA$ replicates semiconservatively

Column $X$	Column $Y$
$(1)$ $DNA$	$(P)$ Most abundant
$(2)$ $m-RNA$	$(Q)$ Various types based on anticodons
$(3)$ $t-RNA$	$(R)$ Carries information as genetic code
$(4)$ $r-RNA$	$(S)$ $A$ specific part acts as a template

Assertion $(A):$ The split gene arrangement represents probably an ancient feature of the genome.
Reason $(R):$ $\text{hnRNA}$ undergoes additional processing called as capping and tailing.
Choose the correct option.
