Question

what is the function of rna polymerase in protein synthesis?
it brings the trna to the ribosome.
it bonds the dna strand.
it unzips the dna strand.
it translates the dna strand.

Explanation:

First, eliminate incorrect options:

1. Bringing tRNA to the ribosome is the role of elongation factors, not RNA polymerase.
2. Unzipping DNA strands is done by helicase, not RNA polymerase.
3. Translating genetic information into protein is carried out by ribosomes, not RNA polymerase.

RNA polymerase functions by binding to a DNA strand at a promoter region, then synthesizing an RNA transcript using the DNA as a template, which is part of transcription in protein synthesis.

Answer:

It bonds the DNA strand.
