1. Hyperbaric oxygen may be used as a treatment for certain types of bacterial infections. In this therapy, the patient is placed in a chamber in which the partial pressure of oxygen is significantly increased, increasing the partial pressure of oxygen in the patient's tissues. This treatment is most likely used for infections with:
2. Which of the following does NOT describe connective tissue cells?
3. Which of the following types of nucleic acid could form the genome of a virus?
I. Single-stranded RNA
II. Double-stranded DNA
III. Single-stranded DNA
4. Which of the following activities occurs in the Golgi apparatus?
5. Mitochondrial DNA is:
6. Which of the following is NOT a function of the smooth endoplasmic reticulum?
7. What is the main function of the nucleolus?
8. Which of the following organelles is surrounded by a single membrane?
9. Which of the following is NOT a difference that would allow one to distinguish a prokaryotic and a eukaryotic cell?
10. Which of the following does NOT contain tubulin?
11. Herpes simplex virus (HSV) enters the human body and remains dormant in the nervous system until it produces an outbreak after exposure to heat, radiation, or other stimuli. Which of the following statements correctly describes HSV?
12. Resistance to antibiotics is a well-recognized medical problem. Which mechanism(s) can account for a bacterium's ability to increase its genetic variability and thus adapt itself to different antibiotics?
13. A bacterial cell is noted to be resistant to penicillin. The bacterium is transferred to a colony that lacks the fertility factor, and the rest of the colony does not become resistant to penicillin. However, the penicillin-resistant cell has also started to exhibit other phenotypic characteristics, including secretion of a novel protein. Which of the following methods of bacterial recombination is NOT likely to account for this change?
14. In Alzheimer's disease, a protein called the amyloid precursor protein (APP) is cleaved to form a protein called β-amyloid. This protein has a β-pleated sheet structure and precipitates to form plaques in the brain. This mechanism of disease is most similar to which of the following pathogens?
15. After infection of a cell, a viral particle must transport itself to the nucleus in order to produce viral proteins. What is the likely genomic content of the virus?
