25. Which of the following statement is correct related to general and gene-specific transcription factors in eukaryotes? (A) TATA-box-binding protein (TBP) binds to the minor groove of DNA, bends the consensus TATA DNA, and is required for most members of class I, II and III genes. (B) For RNAP III, TBP is a component of the general transcription factor TFIIIC. (C) The bZIP transcription factors dimerize through a basic domain and bind to target DNA through a leucine zipper. (D) TFIIE and TFIIH are essential for promoter clearance and transcription elongation. (E) The Cys2His2-zinc finger of TFIIIA is composed of an antiparallel beta-sheet followed by an alpha-helix, and the beta-sheet recognizes and binds to specific DNA sequences in the major groove.
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.
23. Which of the following is true for eukaryotic Class I and III general transcription factors, except: (A) TFIIIB and TFIIIC are required for all "classical" class III genes. (B) TFIIIC is an assembly factor that helps TFIIIB to bind to a region just upstream of the transcription start site. (C) Human SL1 is an assembly factor that helps the UPE-binding factor of RNA polymerase I to bind to the core promoter element. (D) TFIIIA is a zinc finger protein & is required for transcription of the 5S rRNA genes, but not the tRNA genes. (E) For the class I transcription, human SL1 consists of TATA-binding protein (TBP) and TBP-associated factors (TAFs), which are different from TAFs found in TFIID.
