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.

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.

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.

1. Why are action potentials usually conducted in one direction? (A) The nodes of Ranvier conduct potentials in one direction. (B) The brief refractory period prevents reopening of voltage-gated sodium channels. (C) The axon hillock has a higher membrane potential than the terminals of the axon. (D) Voltage-gated channels for both Na+ and K+ open in only one direction.

2. Which of the following statements is an important consequence of the first law of thermodynamics for a living organism? (A) The energy content of an organism is constant. (B) An organism ultimately must obtain all of the necessary energy for life from its environment. (C) The entropy of an organism decreases with time as the organism grows in complexity. (D) Organisms grow by converting energy into organic matter.

3. A newly discovered unicellular organism isolated from acidic mine drainage is found to contain a cell wall, a plasma membrane, two flagella, and peroxisomes. Based just on this information, the organism is most likely_____. (A) a nonmotile prokaryote (B) a motile bacterium (C) a motile archaea (D) a motile eukaryote

4. A patient who underwent cholecystectomy develops steatorrhea after consuming a high-fat meal. Which digestive process is most directly impaired? (A) Protein hydrolysis by pepsin (B) Emulsification of lipids by bile salts (C) Carbohydrate digestion by amylase (D) Absorption of amino acids

5. The nuclear lamina is an array of intermediate filaments that line the inner side of the nuclear membrane. If a chemical treatment caused the lamina to disassemble, what would you expect to be the most likely immediate consequence? (A) Closing of nuclear pores (B) The inability of the nucleus to divide during cell division (C) A loss of genetic information from chromosomes (D) A change in the shape of the nucleus

6. A research team is working on the design of a new drug for the treatment of lung cancer. To be most effective, this drug must specifically enter the cytoplasm of lung cells while not entering the cells of other tissues. Which of the following characteristics would likely enhance the specificity of this drug? (A) The relative hydrophobicity of the drug molecule (B) Phospholipid composition of lung cell plasma membranes (C) Specificity of the drug molecule for binding to the extracellular matrix of lung cells (D) Similarity of the drug molecule to other molecules normally transported lung cells

7. Which of the following statements correctly describes osmosis? (A) Osmosis only takes place in red blood cells. (B) Osmosis is an energy-demanding or "active" process. (C) In osmosis, water moves across a membrane from areas of lower solute concentration to areas of higher solute concentration. (D) In osmosis, solutes move across a membrane from areas of lower water concentration to areas of higher water concentration. 

8. If the adrenal cortex were surgically removed, an increase in the plasma levels of_____ would likely be observed. (A) glucocorticoid hormones (B) epinephrine (C) adrenocorticotropic hormone (ACTH) (D) acetylcholine
