An example of a basal transcription factor is ________.
A) RNA polymerase
B) the TATA-binding protein
C) an enhancer-binding transcription factor
D) a silencer-binding transcription factor
E) a promoter-proximal-binding transcription factor

Question

Quizplus · Accepted Answer

Basal transcription factors are essential for the formation of the pre-initiation complex, which is needed for transcription to occur. The TATA-binding protein (TBP) is a key component of this complex and is considered a basal transcription factor. RNA polymerase is not a basal transcription factor; it is the enzyme that catalyzes the transcription process. Enhancer-binding and silencer-binding transcription factors are not basal factors either; they work to enhance or repress transcription, respectively. A promoter-proximal-binding transcription factor is not specifically classified as a basal transcription factor, although it may be involved in the transcription process.
