The sum total composition of acid-soluble and acid-insoluble fraction represents the entire composition of

Options

A. a) dead cells
B. b) gene pool
C. c) cellular pool
D. d) gene library.

Answer

To solve the question, we need to understand the relationship between acid-soluble and acid-insoluble fractions and what they represent in a biological context.

### Step-by-Step Solution:

1. **Understanding Biomolecules**:
- Living cells are composed of various biomolecules, which include proteins, carbohydrates, lipids, and nucleic acids. These biomolecules can be categorized based on their solubility in acid.

2. **Acid Treatment of Cells**:
- When a living cell is treated with an acid solution, it results in two distinct fractions:
- **Acid-soluble biomolecules**: These are the biomolecules that dissolve in the acid.
- **Acid-insoluble biomolecules**: These are the biomolecules that do not dissolve in the acid.

3. **Composition of Living Cells**:
- The total composition of both the acid-soluble and acid-insoluble fractions represents the entire composition of the living cell. This is often referred to as the "cellular pool," which contains all the essential biomolecules necessary for cellular functions.

4. **Evaluating Options**:
- Now, we look at the provided options:
- **Option A: Dead cells** - This is incorrect as we are discussing living cells.
- **Option B: Gene pool** - This term relates to genetic variation and is not relevant to the biomolecule composition.
- **Option C: Cellular pool** - This is correct as it encompasses the total composition of biomolecules in a living cell.
- **Option D: Gene library** - This is also incorrect as it refers to a collection of genes, not the composition of biomolecules.

5. **Conclusion**:
- The correct answer is **Option C: Cellular pool**, as it accurately describes the sum total of the acid-soluble and acid-insoluble fractions in a living cell.
