Assertion : Together with polysaccharides and polypeptides nucleic acid comprise the true macromolecular fraction of any living tissue or cell.
Reason : Like polysaccharides and polypeptides nucleic acids also have molecular wieght more than 1000 dalton

Options

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

Answer

To analyze the given assertion and reason, we will break it down step by step.

### Step 1: Understanding the Assertion
The assertion states that "Together with polysaccharides and polypeptides, nucleic acids comprise the true macromolecular fraction of any living tissue or cell."

- **Explanation**: This means that in living cells, the major components that are classified as macromolecules include polysaccharides (complex carbohydrates), polypeptides (proteins), and nucleic acids (DNA and RNA). These are essential for the structure and function of cells.

### Step 2: Understanding the Reason
The reason provided is that "Like polysaccharides and polypeptides, nucleic acids also have a molecular weight more than 1000 daltons."

- **Explanation**: This indicates that nucleic acids, similar to polysaccharides and polypeptides, have a high molecular weight, which is a characteristic of macromolecules. Molecules with a molecular weight greater than 1000 daltons are considered macromolecules.

### Step 3: Evaluating the Truth of the Assertion and Reason
- **Assertion**: True. Polysaccharides, polypeptides, and nucleic acids are indeed the true macromolecular components of living tissues.
- **Reason**: True. Nucleic acids do have a molecular weight greater than 1000 daltons, which aligns with the definition of macromolecules.

### Step 4: Determining the Relationship Between Assertion and Reason
- The reason correctly explains why the assertion is true. Both the assertion and the reason are true, and the reason provides a valid explanation for the assertion.

### Conclusion
Both the assertion and reason are true, and the reason is a correct explanation of the assertion. Therefore, the correct answer is that both the assertion and reason are true, and the reason correctly explains the assertion.
