There are several proteins involved in transcription, including transcription factors, regulatory binding proteins, and activators. Their role is to tell RNA polymerase
A) where to start transcribing the DNA.
B) which genes to transcribe.
C) where to stop transcribing the DNA.
D) Both a and b
E) a, b, and c

Question

Quizplus · Accepted Answer

Transcription factors, regulatory binding proteins, and activators play a role in regulating gene expression by binding to specific DNA sequences, which tells RNA polymerase where to start transcribing the DNA and which genes to transcribe. However, they do not usually tell RNA polymerase where to stop transcription. Therefore, options A and B are correct, but option C is incorrect. Therefore, the most appropriate answer is D - both A and B are true statements.
