Assertion :- Genetic codes are unambigous & specific.
Reason : Some amino acids are coded by more than one codon.

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

To solve the question, we need to analyze both the assertion and the reason provided.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "Genetic codes are unambiguous and specific."
- This means that each codon (a sequence of three nucleotides) corresponds to only one specific amino acid. Therefore, the assertion is **true**.

2. **Understanding the Reason**:
- The reason given is "Some amino acids are coded by more than one codon."
- This statement is also true because the genetic code is degenerate, meaning that multiple codons can code for the same amino acid.

3. **Analyzing the Relationship**:
- While both the assertion and the reason are true, the reason does not explain the assertion. The assertion focuses on the specificity of codons to amino acids, while the reason highlights the degeneracy of the code.
- Therefore, the reason is not the correct explanation for the assertion.

4. **Conclusion**:
- Since both the assertion and the reason are true, but the reason does not explain the assertion, the correct answer is: "Both assertion and reason are true but reason is not the correct explanation of the assertion."

### Final Answer:
The correct option is: **Both assertion and reason are true but reason is not the correct explanation of the assertion.**
