Assertion :- The DNA strand which does not code for nothing is referred to as coding stand.
Reason : Coding strand sequence are same as RNA except thymine at the place of uracil.

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 analyze the assertion and reason provided in the question, we will break down the statements step by step.

### Step 1: Understanding the Assertion
- **Assertion**: The DNA strand which does not code for anything is referred to as the coding strand.
- **Analysis**: This statement is incorrect. The DNA strand that does not code for anything is actually called the "template strand." The coding strand is the one that has the same sequence as the mRNA (except for the substitution of thymine for uracil).

### Step 2: Understanding the Reason
- **Reason**: Coding strand sequences are the same as RNA except thymine at the place of uracil.
- **Analysis**: This statement is correct. The coding strand of DNA has a sequence that is complementary to the template strand and identical to the mRNA sequence, with the exception that thymine (T) is present in DNA instead of uracil (U) in RNA.

### Step 3: Conclusion
- Since the assertion is incorrect and the reason is correct, we conclude that the assertion does not logically follow from the reason. Therefore, the correct answer is that the assertion is false, while the reason is true.

### Final Answer:
- The assertion is false, and the reason is true.
