WebMar 26, 2024 · The transcription of bacterial genes driven by DNA-dependent RNA polymerase (RNAP) is the first step in gene expression. Holo RNAP consists of multi-subunit, catalytic core enzyme, formed by the α 2 ββ ′ ω subunits, and the sigma (σ) subunit, which confers the promoter selectivity of the RNAP. Bacteria usually contain …
