WebFeb 4, 2024 · To begin transcribing a gene, RNA polymerase binds to the DNA of the gene at a region called the promoter. A promoter contains DNA sequences that let RNA … WebWhat is it called when the holoenzyme binds to the promoter and transcription begins? Once the holoenzyme is bound to a promoter for a bacterial gene, the DNA double helix is opened by the RNA polymerase, creating two separated strands of DNA. ... Most eukaryotic promoters include a sequence called the TATA box, 30 base pairs upstream of the …
