Question

Quizplus · Accepted Answer

The sigma factor (represented by the symbol σ) is responsible for initiating transcription at the correct site by binding to the promoter region of the DNA. It directs the RNA polymerase to start transcription at the appropriate site and dissociates from the polymerase once transcription has begun. Therefore, Choice E, (F1F1F1S1σF1F1F10), is the correct answer.
