The role of the sigma ($\sigma$) factor in prokaryote transcription is to
A) unwind the DNA during transcription.
B) direct RNA polymerases to bind to different promoter regions.
C) recognize the transcription initiation site.
D) terminate transcription.

Question

Quizplus · Accepted Answer

The sigma factor is a protein needed for the initiation of transcription in prokaryotes. It directs RNA polymerase to specific promoter regions on the DNA, allowing the enzyme to initiate transcription at the correct site.
