The Function of the Core Enzyme of RNA Polymerase Is

Question

The function of the core enzyme of RNA Polymerase is:
A) To recognize and bind RNA polymerase to the transcription initiation or promoter sites in DNA
B) To recognize and bind DNA polymerase to the transcription initiation or promoter sites in RNA
C) catalyze RNA synthesis from DNA templates in vitro
D) To catalyze DNA synthesis from DNA templates in vitro
E) To catalyze DNA synthesis from RNA templates in vitro

Accepted Answer

The core enzyme of RNA Polymerase catalyzes RNA synthesis from DNA templates in vitro. It does not recognize and bind DNA polymerase to the transcription initiation or promoter sites in RNA, nor does it catalyze DNA synthesis from DNA templates in vitro or DNA synthesis from RNA templates in vitro. Its function is solely to synthesize RNA from DNA.
