A : DNA fingerprinting are important to scientists in human genomics.
R: Molecular probe is small DNA segment synthesized in laboratory with know sequence that recognise complementary sequence in RNA.

Options

A. If both Assertion & Reason are true and the reason is the correct explanation of the assertion, then mark
B. If both Assertion & Reason are true and the reason is not the correct explanation of the assertion , then mark
C. If Assertion is ture statement but Reason is false, then mark.
D. If both Assertion and Reason are false statements, then mark.

Answer

### Step-by-Step Solution:

1. **Understanding the Assertion**: The assertion states that "DNA fingerprinting is important to scientists in human genomics."
- **Explanation**: DNA fingerprinting is a technique used to identify individuals based on their unique DNA profiles. It plays a crucial role in human genomics for applications such as paternity testing, forensic science, and genetic diversity studies.

2. **Understanding the Reason**: The reason states that "a molecular probe is a small DNA segment synthesized in the laboratory with a known sequence that recognizes complementary sequences in RNA."
- **Explanation**: A molecular probe is indeed a short strand of DNA or RNA that is designed to bind to a specific sequence of nucleotides in a target RNA or DNA molecule. This binding is based on complementary base pairing, which is essential for various molecular biology techniques, including gene detection and expression studies.

3. **Evaluating the Truth of Assertion and Reason**:
- **Assertion**: True, as DNA fingerprinting is a significant tool in human genomics.
- **Reason**: True, as the definition of a molecular probe is accurate.

4. **Analyzing the Relationship**: The assertion and reason are both true, but the reason does not explain the assertion.
- **Conclusion**: While both statements are correct, the reason provided does not clarify why DNA fingerprinting is important in human genomics.

5. **Final Answer**: The correct answer is that both the assertion and reason are true, but the reason is not the correct explanation of the assertion. Therefore, the answer is option number two.
