How does rna polymerase recognize a gene

WebTranscription is the process by which genetic information stored in the DNA sequence of a gene is copied into a complementary RNA molecule. This RNA molecule can then be used as a template for protein synthesis. Transcription occurs in the nucleus of eukaryotic cells and in the cytoplasm of prokaryotic cells. Transcription is a complex process ... WebBacterial transcription is the process in which a segment of bacterial DNA is copied into a newly synthesized strand of messenger RNA (mRNA) with use of the enzyme RNA polymerase . The process occurs in three main steps: initiation, elongation, and termination; and the end result is a strand of mRNA that is complementary to a single strand of DNA.
