Answer:
RNA polymerase is a multi subunit enzyme that catalyzes the process of transcription.
Step-by-step explanation:
The central dogma of biology has looked at RNA as a messenger molecule, that exports the information coded into DNA out of the nucleus in order to drive the synthesis of proteins in the cytoplasm: DNA → RNA → Protein.
So in other words, it's responsible for copying a DNA sequence into an RNA sequence, during the process of transcription.
