The RNA polymerase I transcribe rRNAs ($28\mathrm{S}, 18\mathrm{S},$ and $5.8\mathrm{S}$), whereas the RNA polymerase III is responsible for transcription of tRNA, $5$S rRNA, and snRNAs (small nuclear RNAs). The RNA polymerase II transcribes a precursor of mRNA, the heterogeneous nuclear RNA (hnRNA).
