What Attaches To The Promoter Region Of DNA In Order For Transcription To Occur? To begin transcribing a gene, RNA polymerase binds to the DNA of the gene at a region called the promoter. Basically, the promoter tells the polymerase where to “sit down” on the DNA and begin transcribing. What binds to the promoter
