Regulatory transcription factors _____.
A)influence the binding of sigma factor to DNA
B)influence the assembly of the basal transcription complex
C)influence the degree of unwinding of DNA at the promoter
D)open the two strands of DNA so RNA polymerase can begin transcription

Question

Quizplus · Accepted Answer

Regulatory transcription factors influence the assembly of the basal transcription complex by interacting with the RNA polymerase and promoter region, leading to changes in the efficiency of transcription initiation. They do not directly influence the binding of sigma factor to DNA, the degree of DNA unwinding, or open the two strands of DNA.
