Bacterial transcription - Wikipedia

Bacterial 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 stran… WebApr 11, 2024 · Whether and how bacterial pathogens inhibit innate immune receptor-driven type I IFN expression remains mostly unknown.
