D) All of the above

Question

Quizplus · Accepted Answer

F1F1F1S1F1F1F10 factors are sigma factors in prokaryotes that are responsible for specific binding to certain promoters. They help to recruit RNA polymerase to the correct promoter region, allowing for transcription to begin at the appropriate site. While these factors may also be involved in other aspects of transcription, their primary function is to ensure accurate initiation of transcription.
