Assertion :- UGG is a chain termination codon.
Reason : It does not code any amino acid.

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 1: Understand the Assertion
The assertion states that "UGG is a chain termination codon." We need to verify if UGG is indeed a termination codon.

### Step 2: Identify the Role of UGG
UGG is a codon in the genetic code. It is important to know that there are specific codons known as stop codons or termination codons, which signal the end of protein synthesis. The known stop codons are UAA, UAG, and UGA. UGG, however, does not belong to this category.

### Step 3: Conclusion on the Assertion
Since UGG is not a termination codon, the assertion is false.

### Step 4: Understand the Reason
The reason states that "It does not code any amino acid." We need to verify if UGG codes for any amino acid.

### Step 5: Identify the Role of UGG Again
UGG actually codes for the amino acid tryptophan. Therefore, the statement that UGG does not code for any amino acid is also false.

### Step 6: Final Evaluation
Both the assertion and the reason are false. Therefore, the correct answer to the question is that both the assertion and the reason are false.

### Final Answer
The correct option is: **Both assertion and reason are false.**
