Question

Quizplus · Accepted Answer

The binding of sigma (a subunit of RNA polymerase) to the promoter region (a sequence of DNA that initiates transcription) is central to the initiation of transcription in prokaryotes. This binding enables RNA polymerase to recognize and bind to the promoter, leading to the unwinding of the DNA double helix and the initiation of RNA synthesis.
