Question

What is the role of the enzyme RNA polymerase in the process of transcription?

A) It creates "start" and "stop" sequences in DNA to control transcription.
B) It transcribes DNA sequences to produce a complementary strand of RNA.
C) It creates a different template for new base-pairing.
D) None of the other answer choices

Answer 1

RNA polymerase transcribes DNA sequences to produce a complementary strand of RNA during the process of transcription.

Step-by-step explanation:

The role of the enzyme RNA polymerase in the process of transcription is to transcribe DNA sequences to produce a complementary strand of RNA. During initiation, RNA polymerase binds to a region of a gene called the promoter and begins synthesis of a new RNA strand using the template DNA strand. During elongation, the polymerase adds new nucleotides to the growing RNA strand, aligning the correct nucleic acid with its complementary base on the DNA. Termination occurs when RNA polymerase crosses a stop sequence in the gene, completing the mRNA strand.
