Can RNA polymerase bind into a sequence within the gene by itself? explain.

RNA polymerase is the main transcription enzyme.

Transcription begins when RNA polymerase binds to a promoter sequence near the beginning of a gene (directly or through helper proteins).

RNA polymerase uses one of the DNA strands (the template strand) as a template to make a new, complementary RNA molecule.

Transcription ends in a process called termination. Termination depends on sequences in the RNA, which signal that the transcript is finished.
