Final answer:
RNA polymerase helps transcribe the DNA strand by synthesizing a complementary RNA molecule using a DNA template.
Step-by-step explanation:
The role of RNA polymerase is to help transcribe the DNA strand. It is an enzyme that catalyzes the formation of an RNA molecule using a DNA template. RNA polymerase binds to the promoter region of the DNA and begins the process of transcription, where it synthesizes a complementary RNA strand that matches the DNA sequence. This RNA molecule is then used to produce proteins during translation.
