E)transcription factors bind to the TATA box sequence

Question

Quizplus · Accepted Answer

The first step during transcription initiation in prokaryotes is the binding of RNA polymerase to the promoter region of DNA. This binding allows the formation of the transcription bubble and subsequent unwinding of the DNA double helix. The formation of a primer and binding of transcription factors occur later in the initiation process.
