Assertion :- There occur 64 codons iin dictionary of genetic code
Reason : genetic code is quadraplete

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 evaluate the assertion and the reason provided.

### Step 1: Analyze the Assertion
The assertion states that "There occur 64 codons in the dictionary of genetic code."
- In genetics, a codon is a sequence of three nucleotides that corresponds to a specific amino acid or a stop signal during protein synthesis.
- There are indeed 64 possible combinations of these triplet codons (4 nucleotides: A, U, G, C; and 3 positions: 4^3 = 64).
- Out of these 64 codons, 61 codons code for amino acids, and 3 are stop codons.

**Conclusion for Assertion**: The assertion is **True**.

### Step 2: Analyze the Reason
The reason states that "genetic code is quadruplet."
- The genetic code is actually based on triplets, not quadruplets. Each codon consists of three nucleotides, which means the genetic code is triplet in nature.
- Therefore, the statement that the genetic code is quadruplet is incorrect.

**Conclusion for Reason**: The reason is **False**.

### Step 3: Determine the Relationship
Now we need to determine the relationship between the assertion and the reason:
- The assertion is true, but the reason is false.

### Final Conclusion
Based on the analysis:
- The correct answer is that the assertion is true, but the reason is false.

### Answer: Option 3 (Assertion is true but Reason is false)
