$RNA$ polymerase $I$

Vedclass · Answer

(A) In eukaryotes,there are three types of $RNA$ polymerases involved in transcription:$1$. $RNA$ polymerase $I$ is responsible for the transcription of $rRNA$ ($28S$,$18S$,and $5.8S$).$2$. $RNA$ polymerase $II$ is responsible for the transcription of precursor of $mRNA$ (heterogeneous nuclear $RNA$ or $hnRNA$).$3$. $RNA$ polymerase $III$ is responsible for the transcription of $tRNA$,$5S$ $rRNA$,and $snRNA$.Therefore,$18S$ $rRNA$ is synthesized by $RNA$ polymerase $I$.

Which enzyme is responsible for the synthesis of $18S$ $rRNA$?
