The role of mitosis is not merely to divide a cell into two daughter cells but to ensure genetic continuity from one cell generation to another cell generation. The mechanism ensuring genetic continuity is

Options

A. formation of cells with new chromosomes
B. formation of two daughter cells
C. formation of two cells with identical DNA
D. halving the chromosome number between the two new cells.

Explanation

To address the question regarding the role of mitosis in ensuring genetic continuity from one cell generation to another, we can break down the solution into clear steps:

### Step-by-Step Solution:

1. **Understanding Mitosis**: Mitosis is a type of cell division that results in two daughter cells that are genetically identical to the parent cell. It is crucial for growth, repair, and maintenance of multicellular organisms.

2. **Purpose of Mitosis**: The primary purpose of mitosis is not only to divide the cell but also to ensure that each daughter cell receives an exact copy of the parent cell's genetic material. This is essential for maintaining genetic continuity across generations of cells.

3. **Chromosomal Distribution**: During mitosis, the chromosomes are duplicated and then evenly distributed to the two daughter cells. This ensures that both daughter cells have the same number and type of chromosomes as the parent cell.

4. **Identical DNA in Daughter Cells**: The mechanism that ensures genetic continuity is the formation of two cells with identical DNA. This means that the genetic information is preserved and passed on from one generation of cells to the next.

5. **Conclusion**: Therefore, the correct answer to the question is that the mechanism ensuring genetic continuity during mitosis is the formation of two cells with identical DNA.

### Final Answer:
The mechanism ensuring genetic continuity is the formation of two cells with identical DNA (Option 3).
