Assertion :- TAC is anticodon of AUG codon.
Reason : Codon and anticodon are non-complementary to each other.

Options

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

Answer

To solve the question, we will analyze both the assertion and the reason statements provided.

### Step 1: Understand the Assertion
The assertion states that "TAC is the anticodon of AUG codon."
- The codon AUG is found on mRNA and codes for the amino acid Methionine.
- The anticodon is found on tRNA and must be complementary to the codon on the mRNA.

### Step 2: Determine the Complementary Anticodon
To find the correct anticodon for the AUG codon:
- The codon AUG consists of the bases A (Adenine), U (Uracil), and G (Guanine).
- The complementary bases are:
- A pairs with U
- U pairs with A
- G pairs with C
- Therefore, the complementary anticodon for AUG would be UAC, not TAC.

### Step 3: Analyze the Reason
The reason states that "Codon and anticodon are non-complementary to each other."
- This statement is incorrect because codons and anticodons must be complementary to ensure proper pairing during protein synthesis.

### Conclusion
Both the assertion and the reason are incorrect:
- The assertion is incorrect because TAC is not the anticodon for AUG; it is UAC.
- The reason is incorrect because codons and anticodons are complementary to each other.

Thus, the correct answer is that both the assertion and the reason are false.

### Final Answer
Both the assertion and the reason are incorrect.
