Assertion :- The VNTR belongs to a class of satellite DNA referred to as mini-satelite.
Reason : The mini-satelite numbers remains same from chromsome to chromsome in an individual.

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion.
B. If both Assertion & Reason are trur but Reason is not a correct explanation of the Assertion.
C. If Assertion is True but the Reason is Flase.
D. If both Assertion & Reason are false.

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion**: The assertion states that VNTR (Variable Number Tandem Repeats) belongs to a class of satellite DNA referred to as mini-satellite.
- **Explanation**: VNTRs are indeed a type of repetitive DNA that can be classified as mini-satellites. Mini-satellites are characterized by repeating sequences of DNA that can vary in number among individuals.

2. **Understanding the Reason**: The reason given is that the mini-satellite numbers remain the same from chromosome to chromosome in an individual.
- **Explanation**: This statement is incorrect. The number of mini-satellite repeats can vary between different chromosomes and also among different individuals. Therefore, mini-satellite numbers do not remain the same across chromosomes in an individual.

3. **Evaluating the Truth of Assertion and Reason**:
- The assertion is true because VNTRs are classified as mini-satellites.
- The reason is false because mini-satellite numbers do not remain constant across chromosomes.

4. **Conclusion**: Since the assertion is true and the reason is false, the correct answer is that the assertion is true, but the reason is false.

**Final Answer**: Assertion is true, but the reason is false.
