Which of the following is not correct regarding gingival retraction cord? a. If the cord is treated with an agent such as Hemodent® it should be left in place for 5 to 7 minutes before taking the final impression. b. Gingival retraction cords with epinephrine are beneficial as the epinephrine causes vasoconstriction and reduction in bleeding. c. The use of gingival retraction cord displaces the gingiva around the preparation so impression material can flow into that area. d. The gingival retraction cord is placed subgingivally with a Balshi packer or other packing instrument.

Which of the following statements about gel-filtration chromatography (GFC) is incorrect? a. GFC can be used to remove ammonium sulfate ions after fractionation b. Bio-gel P-30 can be used for protein standards from 10kDa-120kDa c. GFC can be used to estimate molecular weight of globular proteins d. A pH 5.00 elution buffer can be used for agarose gels 2. A student attempted to characterize a protein extract using SDS-PAGE with 150 V. Upon staining and destaining, the gel profile showed the band which stayed at the top of the resolving gel. Which of the following is the best to do to troubleshoot the problem? a. Increase the voltage c. Increase the protein concentration b. Decrease the acrylamide concentration d. Decrease the volume of the loading buffer 3. An ideal visualization of gel in an electrophoresis is the presence of clear bands, but sometimes the bands smear (or a blurred streak is present instead of a clear band) due to improper execution of procedure. Which of the following may cause smearing of bands? I. The stacking gel has a higher acrylamide content and lower pH than the resolving gel. II. Isopropyl alcohol is added as an overlay to level the surface of the stacking gel and avoid dehydration. III. Acrylamide is decomposed creating free radicals that initiate the polymerization. IV. TEMED controls the rate at which the gel will harden. a. I only b. I and II c. III and IV d. IV only 4. Which of the following is/are CORRECTLY matched? a. Methanol and acetic acid: prevent the proteins from being washed out during destaining b. Bromophenol blue: protein dye which binds to the sample during staining c. B-mercaptoethanol: acts as protein denaturant by disrupting the non-covalent interactions in proteins d. Glycine: used to stack the proteins and has a lower migration rate at fully deprotonated form

Which of the following statements are incorrect? I. The spinal cord extends from the medulla oblongata superiorly to the level of L2 inferiorly. II. The smaller bifurcation of the spinal nerve, the dorsal ramus, supplies only deep back muscles. III. The inferior end of the spinal cord is termed conus medullaris for the conical shape it exhibits. IV. The spinal cord receives blood supply from arteries clinically referred to as Batson's arteries. Select one: a. Only two of the above. b. Only one of the above. c. Only three of the above. d. All of the above. e. None of the above. Which is correct regarding the spinal cord? Select one: a. White matter is composed mainly of nerve fibers (mainly axons) within the CNS. b. Dorsal and ventral horns are motor and sensory, respectively. c. The dorsal root contains cell bodies of motor neurons. d. A ganglion is a collection of cell bodies within the peripheral nervous system. e. There are 31 spinal nerves.

Which of the following is incorrect about 2,3-bisphosphoglycerate (BPG)? It increases hemoglobin's affinity for oxygen. It binds only to the tense (deoxy) conformation of hemoglobin. It binds positively charged groups between the four subunits of hemoglobin. It prevents the binding of oxygen to hemoglobin. It is highly negatively charged. Which of the following is incorrect? Two thiol groups of Met can undergo oxidation and form a disulfide bond. The aromatic amino acids absorb UV light and are fluorescent. The side chain of Pro forms a ring with its amino group. None of the above. Which of the following is incorrect about the heme group? It contains an iron atom. It is a prosthetic group found in myoglobin and hemoglobin. It is an oxygen-binding group. It is mostly planar and hydrophilic. It is found in the hydrophobic pocket of myoglobin and the subunits of hemoglobin. Which of the following is incorrect about the alpha-helix? H-bonds are between the C=O group and the N-H group four residues farther along the helix. It can be easily identified in the "ribbon" representation. Its major stabilizing force is the hydrophobic effect. H-bonds along the helical axis stabilize the structure. There are 3.6 amino acid residues per turn.
