Question

Quizplus · Accepted Answer

Transcription is the process by which RNA polymerase binds to the promoter region on DNA and synthesizes a complementary RNA strand. The correct choice is B because RNA polymerase is responsible for initiating transcription, and it needs to have access to the double-stranded DNA and be able to bind to the promoter region of the gene in order for the process to begin. None of the other choices mention RNA polymerase or the importance of the promoter region.
