Vedclass · Answer

(A) In eukaryotes,there are three main types of $RNA$ polymerases involved in transcription:$1$. $RNA$ polymerase $I$ is responsible for the transcription of $r-RNA$ ($28S$,$18S$,and $5.8S$).$2$. $RNA$ polymerase $II$ is responsible for the transcription of the precursor of $m-RNA$,which is $hnRNA$ (heterogeneous nuclear $RNA$).$3$. $RNA$ polymerase $III$ is responsible for the transcription of $t-RNA$,$5S$ $r-RNA$,and $snRNA$ (small nuclear $RNA$).Therefore,the removal of $RNA$ polymerase $I$ will specifically affect the synthesis of $r-RNA$.
