HomeBacteriophages and Antibiotic Resistance Quiz 2

1. What is the primary target of bacteriophages?

A. Fungi
B. Viruses
C. Bacteria

2. Which of the following is NOT a characteristic of bacteriophages?

A. They are composed of DNA or RNA
B. They can replicate outside of host cells
C. They have a specific host range

3. What is the role of lytic bacteriophages?

A. To integrate their DNA into the host genome
B. To establish a long-term symbiotic relationship with the host
C. To infect and kill the host bacterium

4. What is the term for a bacterium that is infected by a bacteriophage?

A. Host
B. Vector
C. Carrier

5. How do bacteriophages recognize their specific host bacteria?

A. By binding to specific receptors on the bacterial cell surface
B. By diffusing randomly and infecting any bacterium they encounter
C. By using their flagella to swim towards the host bacterium

6. How do temperate bacteriophages differ from lytic bacteriophages?

A. Temperate bacteriophages only infect gram-negative bacteria
B. Temperate bacteriophages do not kill the host bacterium upon infection
C. Temperate bacteriophages cannot integrate their DNA into the host genome

7. How do bacteriophages replicate within a host bacterium?

A. By undergoing binary fission like bacteria
B. By hijacking the host cell’s machinery for replication
C. By releasing enzymes that break down the bacterial DNA

8. What is the term for the burst of host bacterium that occurs during the lytic cycle?

A. Lysis
B. Exocytosis
C. Endocytosis

9. What is the main benefit of using bacteriophages for phage therapy?

A. They have a broad host range, allowing treatment of various bacterial infections
B. They are easily manufactured in large quantities
C. They do not elicit an immune response in humans

10. What is the main challenge in using bacteriophages for phage therapy?

A. The limited availability of specific bacteriophages for different bacterial strains
B. The high cost of producing bacteriophages on a large scale
C. The risk of the bacteriophages becoming resistant to antibiotics
