The bacteriophage contains an enzyme called _ which digest the cell wall of bacterium.
Correct answer: A. Lysozyme
- A. Lysozyme
- B. Hemagglutinin
- C. Neuraminidae
- D. Integrase
Explanation
The bacteriophage is a virus that infects bacteria. It uses an enzyme called lysozyme to break down the cell wall of the bacterium it targets. This allows the bacteriophage to enter the bacterial cell and take over its machinery to replicate itself. Lysozyme is like a key that helps the bacteriophage unlock and invade the bacterium. It's a fascinating example of how viruses have evolved to exploit their host's defenses.

About Viruses
Viruses are acellular infectious particles made of genetic material enclosed by a protein capsid, sometimes with a lipid envelope. Their replication depends on a host cell and may follow lytic or lysogenic cycles, so viral structure and reproduction differ fundamentally from those of cellular organisms such as bacteria.
