The proces of transformation is not affected by which of the following enzymes?
A. Dnase ,B. Rnase
c. Peptidase , D. Lipase

Options

A. A,B
B. A, B, C, D
C. B, C, D
D. A, B, C

Explanation

To solve the question regarding which enzyme does not affect the process of transformation, we can follow these steps:

### Step 1: Understand the Process of Transformation
Transformation is a process where DNA from one cell is taken up by another cell, leading to a change in the latter's characteristics. This process was crucial in demonstrating that DNA is the genetic material.

**Hint:** Remember that transformation involves the uptake of DNA by a cell.

### Step 2: Identify the Enzymes Listed in the Options
The options provided are:
- A. DNase (DNA digesting enzyme)
- B. RNase (RNA digesting enzyme)
- C. Peptidase (protein digesting enzyme)
- D. Lipase (fat digesting enzyme)

**Hint:** Consider the function of each enzyme in relation to DNA.

### Step 3: Analyze the Effect of Each Enzyme on Transformation
- **DNase:** This enzyme digests DNA. If DNA is digested, transformation cannot occur because the genetic material is destroyed.
- **RNase:** This enzyme digests RNA. Since transformation involves DNA, the presence of RNase does not affect the process.
- **Peptidase:** This enzyme digests proteins. Similar to RNase, it does not affect the DNA needed for transformation.
- **Lipase:** This enzyme digests fats. It has no role in the transformation process as it does not interact with DNA.

**Hint:** Focus on which enzymes specifically target DNA and which do not.

### Step 4: Determine Which Enzyme Does Not Affect Transformation
From the analysis:
- DNase inhibits transformation.
- RNase, Peptidase, and Lipase do not affect transformation.

Thus, the enzymes that do not affect transformation are RNase, Peptidase, and Lipase. However, since the question asks for the one that does not affect it at all, we can conclude that:

**Answer:** C. Peptidase and D. Lipase do not affect transformation, but since we need to choose one option, the best choice is **C. Peptidase** as it is least related to DNA.

### Final Answer:
C. Peptidase
