Vedclass · Answer

(D) In eukaryotes,the primary transcript produced by $RNA$ polymerase $II$ is known as heterogeneous nuclear $RNA$ $(hnRNA)$.$hnRNA$ is a precursor to messenger $RNA$ $(mRNA)$.It is significantly longer than the mature $mRNA$ because it contains both exons (coding sequences) and introns (non-coding sequences).Typically,$hnRNA$ molecules are large,often containing $200$ or more nucleotides,and undergo processing such as splicing,capping,and tailing to become functional $mRNA$.

Direction of $RNA$ synthesis	Direction of reading of the template $DNA$
$A$. $5'-3'$	$3'-5'$
$B$. $3'-5'$	$5'-3'$
$C$. $5'-3'$	$5'-3'$
$D$. $3'-5'$	$3'-5'$

Heterogeneous nuclear $RNA$ $(hnRNA)$ is characterized by which of the following?
