Vedclass · Answer

(B) In eukaryotic cells, there are three main types of $RNA$ polymerases responsible for transcription:$1$. $RNA$ polymerase $I$ transcribes $rRNA$ ($28S, 18S,$ and $5.8S$).$2$. $RNA$ polymerase $II$ transcribes the precursor of $mRNA$, which is known as heterogeneous nuclear $RNA$ $(hnRNA)$.$3$. $RNA$ polymerase $III$ transcribes $tRNA$, $5S$ $rRNA$, and $snRNA$.Therefore, $RNA$ polymerase $II$ is responsible for synthesizing precursor $mRNA$.

Which of the following enzymes synthesizes precursor $mRNA$?
