Question

Eukaryotic cells produce three distinct RNA polymerases: pol I, pol II, and pol III. Which of the following statements is NOT true about eukaryotic RNA polymerases?

A) Pol II, with twelve subunits on its own, is capable of initiating transcription.

B) Pol III is responsible for the transcription of all tRNAs.

C) Pol I carries out the transcription of the 45S pre-rRNA transcript.

D) Pol III is responsible for the transcription of ribosomal 5S rRNA.

Answer 1

The answer is A) Pol II, with twelve subunits on its own, is capable of initiating transcription. because it is composed with 12 subunits and due to incapable of specific promoter recognition it can't initiate transcription.
