The TFIID complex is formed by
A)TATA-binding protein TBP and TAFs.
B)TATA-binding protein TBP,TAFs and RNA pol II.
C)TAFs and the core promoter.
D)TATA-binding protein and activators.

Question

Quizplus · Accepted Answer

The TFIID complex is formed by the TATA-binding protein (TBP) and TBP-associated factors (TAFs). RNA polymerase II (RNA pol II) is recruited to the complex later in the transcription initiation process. Therefore, choice B is incorrect. Choice C is also incorrect as the TAFs are part of the TFIID complex, not the core promoter. Choice D is incorrect as activators are not part of the TFIID complex.
