During DNA purification which enzyme is used to treat plant cells?

Options

A. Lysozyme
B. Cellulase
C. Chitinase
D. Cutinase

Answer

To answer the question regarding which enzyme is used to treat plant cells during DNA purification, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Context**: DNA purification involves breaking down cell walls to extract DNA. Different types of cells have different structures, requiring specific enzymes for effective treatment.

2. **Identifying the Enzymes**: The enzymes mentioned are:
- **Lysozyme**: Typically used for bacterial cells.
- **Cellulase**: Specifically targets plant cell walls.
- **Chitinase**: Used for fungal cells.
- **Qitinase**: Also works on fungal cells.

3. **Analyzing the Function of Each Enzyme**:
- **Lysozyme**: Breaks down peptidoglycan in bacterial cell walls.
- **Cellulase**: Breaks down cellulose, which is a major component of plant cell walls.
- **Chitinase**: Breaks down chitin, found in fungal cell walls.
- **Qitinase**: Similar to chitinase, it acts on fungal cells.

4. **Determining the Correct Enzyme**: Since the question specifically asks about plant cells, we focus on the enzyme that acts on plant cell walls.

5. **Conclusion**: The enzyme that is used to treat plant cells during DNA purification is **Cellulase**.

### Final Answer:
The enzyme used to treat plant cells during DNA purification is **Cellulase**.
