What is the role of RNA polymerase in transcription?
A)RNA polymerase binds the DNA promoter and builds an mRNA molecule.
B)RNA polymerase catalyzes the unwinding of the DNA double helix.
C)RNA polymerase carries the code for the amino acid in a sequence of nucleotides.
D)RNA polymerase signals the end of the mRNA molecule.

Question

Quizplus · Accepted Answer

RNA polymerase binds to the DNA promoter and uses the template strand of DNA to synthesize a complementary mRNA molecule during transcription. It does not catalyze the unwinding of the DNA double helix, nor does it carry the code for amino acids or signal the end of the mRNA molecule.
