Without __________, the core RNA polymerase binds and releases DNA at random.
A) initiation factor
B) Shine-Dalgarno sequence
C) sigma factor
D) peptidyltransferase
E) release factor

Question

Quizplus · Accepted Answer

Sigma factors are required for the proper binding of RNA polymerase to specific promoter regions on DNA, without which the RNA polymerase would bind and release DNA at random. Initiation factors and Shine-Dalgarno sequences are involved in translation, not transcription. Peptidyltransferase and release factors are involved in protein synthesis, not transcription.
