Which of the following is required for formation of the transcription initiation complex in eukaryotes?
A)binding of a transcription factor to the TATA box,recruitment of additional transcription factors,and recruitment of RNA polymerase II
B)binding of a transcription factor to the operon,recruitment of additional transcription factors,and recruitment of RNA polymerase III
C)binding of a single transcription factor to the TATA box and recruitment of RNA polymerase II
D)binding of RNA polymerase II to the TATA box and core promoter

Question

Quizplus · Accepted Answer

The formation of the transcription initiation complex in eukaryotes involves the binding of a specific transcription factor to the TATA box, which then recruits additional transcription factors and ultimately RNA polymerase II to initiate transcription. Option B is incorrect as operons are a feature of prokaryotic gene regulation, not eukaryotic. Option C is incorrect as multiple transcription factors are required for the formation of the complex. Option D is incorrect as the core promoter is also required for the formation of the complex, not just the TATA box.
