24. Which of the following statement is correct in eukaryotic transcription?
(A) Yeast Gcn4 controls amino acid metabolism, containing a domain using the basic region to bind to DNA and helix-loop-helix to form a protein dimer.
(B) The carboxyl-terminal domain of RNA polymerase is phosphorylated prior to the formation of the initiation complex.
(C) By adding of excess acetyltransferase to in vitro transcription assay, it is likely lead to a tighter association of histone with DNA, resulting in reduced transcription.
(D) TAF1 of the general transcription factor TFIID is a helicase and a histone acetyltransferase.
(E) The high mobility group protein (HMG I(Y)) plays a role in interferon-ẞ (IFN-ẞ) transcription by bending the DNA, causing more activators to bind and interact with each other to enhance transcription.
