$DNA$ dependent $RNA$ polymerase

Vedclass · Answer

(B) In prokaryotes,the process of transcription is carried out by a single type of enzyme known as $DNA$ dependent $RNA$ polymerase.This enzyme is responsible for all three stages of transcription:$1$. Initiation: The enzyme binds to the promoter site on the $DNA$ template with the help of a sigma $(\sigma)$ factor.$2$. Elongation: The enzyme facilitates the polymerization of ribonucleotides to form the $RNA$ chain.$3$. Termination: Upon reaching the terminator sequence,the enzyme dissociates from the $DNA$ template with the help of a rho $(\rho)$ factor.Therefore,$DNA$ dependent $RNA$ polymerase is the only enzyme required for the entire process.

Column-$I$ (Enzyme)	Column-$II$ (Product)
$P$. $RNA$ polymerase-$I$	$I$. $rRNA$ $(18S, 28S, 5.8S)$
$Q$. $RNA$ polymerase-$II$	$II$. $tRNA, 5S rRNA, snRNAs$
$R$. $RNA$ polymerase-$III$	$III$. $hnRNA$

Which is the "Only enzyme" that has the "Capability" to catalyse initiation,elongation,and termination in the process of transcription in prokaryotes?
