Assertion :- The DNA strand which does not code for anything is referred to as coding strand.
Reason :- Coding strand sequence are same as RNA and this strand contain uracil at the place of thymine.

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 need to analyze the assertion and the reason provided.

### Step-by-Step Solution:

1. **Understanding the Assertion**:
- The assertion states that "The DNA strand which does not code for anything is referred to as coding strand."
- This is incorrect. The coding strand is actually the strand of DNA that has the same sequence as the mRNA (except for the substitution of uracil for thymine). The strand that does not code for anything is typically referred to as the non-coding strand or template strand.

2. **Understanding the Reason**:
- The reason states that "Coding strand sequences are the same as RNA and this strand contains uracil at the place of thymine."
- This statement is partially correct. The coding strand does indeed have a sequence that is the same as the mRNA (except for the uracil substitution). However, the coding strand itself contains thymine, not uracil. Uracil is found in RNA, not in the DNA coding strand.

3. **Conclusion**:
- Since the assertion is incorrect and the reason is also incorrect (though it has a true component regarding the sequence similarity), we conclude that:
- The assertion is false.
- The reason is false.

4. **Final Answer**:
- The correct answer is that the assertion is false and the reason is false.
