Smallest segment of genetic material affected by mutation is

Options

A. Recon
B. Cistron
C. Muton
D. Exon

Answer

To solve the question regarding the smallest segment of genetic material affected by mutation, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Question**: The question asks for the smallest segment of genetic material that can be affected by a mutation. This means we need to identify the basic unit of genetic material that can undergo changes.

2. **Identify Key Terms**: The options provided are:
- A. Recon
- B. Cistron
- C. Muton
- D. Axon

3. **Analyze Each Option**:
- **Recon**: This is a unit of recombination, which does not specifically refer to the smallest segment affected by mutation.
- **Cistron**: This term refers to a unit of protein synthesis, which is larger than the smallest segment affected by mutation.
- **Muton**: This is defined as the smallest segment of genetic material that can be altered by mutation. It is the correct term for what the question is asking.
- **Axon**: This term typically refers to a part of a neuron and is not relevant to genetic material.

4. **Conclusion**: Based on the analysis, the correct answer is **C. Muton**. This is the smallest segment of genetic material that can be affected by mutation.

### Final Answer:
The smallest segment of genetic material affected by mutation is **C. Muton**.
