In E. coli, if RNA polymerase is missing ________, then transcription initiation would not occur at the appropriate initiation sites.
A) amino acids
B) mRNA
C) sigma
D) the core enzyme

Question

Quizplus · Accepted Answer

Sigma is a subunit of RNA polymerase in E. coli that helps to recognize the appropriate initiation sites for transcription. Without sigma, the polymerase would not be able to initiate transcription effectively, which means transcription initiation would not occur at the appropriate initiation sites. The other options listed do not directly affect transcription initiation in this way.
