Which RNA polymerase in eukaryotes transcribes 5S rRNA, tRNA and snRNAs?
A{'text': 'RNA polymerase I', 'label': 'A'}
B{'text': 'RNA polymerase II', 'label': 'B'}
C{'text': 'Mitochondrial RNA pol', 'label': 'C'}
D{'text': 'RNA polymerase III', 'label': 'D'}
Answer & Solution
Correct answer: D. {'text': 'RNA polymerase III', 'label': 'D'}
Pol I -> 28S, 18S, 5.8S rRNAs. Pol II -> hnRNA (mRNA precursor). Pol III -> tRNA, 5S rRNA and snRNAs. Organellar polymerases are separate.
