An enzyme found at the tip of tail of bacteriophages is

Options

A. protease
B. lysozyme
C. replicase
D. reverse transcriptase

Answer

**Step-by-Step Solution:**

1. **Understanding Bacteriophages**: Begin by recognizing that bacteriophages are viruses that specifically infect bacteria. They consist of a head, tail, and tail fibers, which are essential for attaching to and penetrating bacterial cells.

2. **Identifying the Enzyme**: The question asks for an enzyme located at the tip of the tail of bacteriophages. This enzyme is crucial for the bacteriophage's ability to infect its host.

3. **Role of the Enzyme**: The enzyme found at the tip of the tail is known as lysozyme. It plays a significant role in the lytic cycle of bacteriophages, which involves the destruction of the host cell.

4. **Function of Lysozyme**: Lysozyme has two primary functions:
- It creates a hole in the bacterial cell wall, allowing the bacteriophage to inject its genetic material into the host cell.
- It digests the cell wall of the bacteria, leading to the lysis (breaking open) of the host cell, which releases new virions (virus particles) into the environment.

5. **Conclusion**: Based on the functions and location of the enzyme, we conclude that the enzyme found at the tip of the tail of bacteriophages is lysozyme.

**Final Answer**: The enzyme found at the tip of the tail of bacteriophages is **lysozyme**.
