Which of the following is not a significant aspect of mitosis ?

Options

A. It introduce variations
B. It replaces old or worn out cells
C. It helps in healing wounds
D. It maintains genetic stability

Answer

To solve the question "Which of the following is not a significant aspect of mitosis?", we need to analyze the provided options and understand the functions of mitosis.

### Step-by-Step Solution:

1. **Understanding Mitosis**: Mitosis is a type of cell division that results in two identical daughter cells. It is essential for growth, repair, and maintenance of tissues in multicellular organisms.

2. **Analyzing the Options**:
- **Option A: It induces variations**: Mitosis produces identical cells, so it does not induce variations. This is a characteristic of meiosis, which is responsible for genetic diversity through the formation of gametes.
- **Option B: It replaces old or worn out cells**: This is a significant aspect of mitosis. When cells die or become damaged, mitosis helps produce new cells to replace them.
- **Option C: It helps in the healing moments**: Mitosis plays a crucial role in healing wounds by producing new cells to replace the damaged ones.
- **Option D: It maintains genetic stability**: Mitosis ensures that the genetic material is accurately copied and distributed to the daughter cells, thus maintaining genetic stability.

3. **Identifying the Incorrect Option**: From the analysis, we see that option A ("It induces variations") is not a significant aspect of mitosis. Instead, it is a function of meiosis.

4. **Conclusion**: The correct answer to the question is **Option A: It induces variations**.
