In eukaryotes the ribosomal RNA genes are transcribed by
-
- Reverse transcriptase
- RNA dependent RNA polymerase
- RNA polymerase I
- RNA polymerase III
Correct Option: C
RNA polymerase I (also called Pol I) is, in higher eukaryotes, the enzyme that only transcribes ribosomal RNA (but not 5S rRNA, which is synthesized by RNA Polymerase III), a type of RNA that accounts for over 50% of the total RNA synthesized in a cell.
