What is the role of RNA polymerase III in the process of transcription in Eukaryotes?
Transcription of only snRNAs
Transcription of rRNAs (28S, 18S and 5.8S)
Transcription of tRNA, 5 srRNA and snRNA
Transcription of precursor of mRNA
According to the text regarding transcription in eukaryotes, there is a clear division of labour among the three nuclear RNA polymerases. RNA polymerase III is responsible for transcription of tRNA, 5S rRNA, and snRNAs (small nuclear RNAs). RNA polymerase I transcribes rRNAs (28S, 18S, and 5.8S), and RNA polymerase II transcribes the precursor of mRNA (hnRNA).
