試題詳解

11.Which statement is true for the general transcription factors in eukaryotic
organisms?
(A) TFIIE, TFIIF and TFIIH are not essential for transcription elongation, but
they are required for promoter clearance.
(B) The core-binding factor is the fundamental transcription factor required to
recruit RNA polymerase I.
(C) During transcription elongation, RNA polymerases may pause at specific
sites near promoters, and this pause can be reversed by TFIIB.
(D) Transcription of the 5S rRNA gene requires TFIIIA and TFIIIB, but not
TFIIIC.

(E) TAF2 and TAF5 can bind to TATA-less promoters that contains the Inr and
DPE promoter elements to ensure the whole TFIID binding to the promoter.
