What is the agent of transformation in bacteria

Options

A. DNA
B. RNA
C. Protein
D. Murein

Answer

**Step-by-Step Solution:**

1. **Understanding Transformation**:
- Transformation in bacteria refers to the process where genetic material is transferred from one bacterial strain to another without direct physical contact. This process allows for genetic variation among bacterial populations.

2. **Identifying the Agent of Transformation**:
- In the context of transformation, the genetic material that is transferred is typically DNA. The donor DNA is taken up by the recipient cell and can become a stable part of its genome.

3. **Excluding Other Options**:
- RNA and proteins do not play a role in the transformation process. While RNA is involved in other cellular processes, it is not the agent of transformation. Similarly, proteins do not serve as the genetic material that is transferred during transformation.

4. **Conclusion**:
- Based on the understanding of transformation and the role of genetic material, the agent of transformation in bacteria is DNA.

**Final Answer**: The agent of transformation in bacteria is DNA.
