What steps are necessary for eukaryotic transcription to begin?
A)Transcriptional activator proteins bind to enhancers.
B)General transcription factors bind to the promoter.
C)General transcription factors and sigma factor bind to the promoter.
D)DNA looping brings transcriptional activator proteins, general transcription factors, sigma factor and RNA Pol II together.
E)DNA looping brings transcriptional activator proteins, general transcription factors, mediator complex and RNA Pol II together.

Question

Quizplus · Accepted Answer

Transcription in eukaryotes begins with transcriptional activator proteins binding to enhancers (A), general transcription factors binding to the promoter (B), and DNA looping bringing together transcriptional activator proteins, general transcription factors, the mediator complex, and RNA Polymerase II (E). Sigma factor is not involved in eukaryotic transcription (C,D).
