Question:
Identify the phage that attacks a host cell but do not destroy it immediately
Identify the phage that attacks a host cell but do not destroy it immediately
Show Hint
Temperate phage = lysogenic cycle = no immediate cell lysis.
Updated On: Jul 18, 2026
- Virulent phage
- Mycophage
- Temperate phage
- Zoophage
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding bacteriophages.
Bacteriophages are viruses that infect bacteria. They can follow two types of life cycles: lytic cycle and lysogenic cycle. Their behavior determines whether the host cell is destroyed immediately or not.
Step 2: Virulent phage characteristics.
Virulent phages strictly follow the lytic cycle. They rapidly multiply inside the host cell and cause immediate destruction of the bacterial cell after replication.
Step 3: Temperate phage behavior.
Temperate phages can integrate their genetic material into the host genome and remain dormant. This lysogenic phase does not immediately destroy the host cell.
Step 4: Comparison with other options.
Mycophages infect fungi and zoophages infect animals, but neither describes the life-cycle behavior asked in the question.
Step 5: Biological significance.
Temperate phages are important in genetic transfer and bacterial evolution because they can transfer genes between bacteria through lysogeny.
Step 6: Final conclusion.
Thus, the phage that does not immediately destroy the host cell is a temperate phage.
