Vedclass · Answer

(A) Statement-$I$ is correct: The presence of split genes (introns and exons) is considered an ancient feature of the genome,often referred to as the 'exon theory of genes'.Statement-$II$ is correct: During the process of post-transcriptional modification (splicing),the non-coding sequences known as introns are removed,and the coding sequences (exons) are joined together to form mature or processed $	ext{mRNA}$. Therefore,introns do not appear in the final mature $	ext{RNA}$.

List-$I$	List-$II$
$A$. Monocistronic gene	$I$. Coding sequence
$B$. Polycistronic gene	$II$. Intervening sequence
$C$. Exons	$III$. Mostly prokaryotes
$D$. Introns	$IV$. Mostly eukaryotes

Statement-$I$: The split gene arrangements represent probably an ancient feature of the genome.
Statement-$II$: Introns or intervening sequences do not appear in mature or processed $\text{RNA}$.
