Which symbol represents the mitotic cell division?

Options

A. `2nrarr2n`
B. `2nrarrn`
C. `nrarr2n`
D. `n+nrarr2n`

Explanation

To determine which symbol represents mitotic cell division, we need to understand the characteristics of mitosis and the symbols used to denote the ploidy of cells involved.

### Step-by-Step Solution:

1. **Understanding Mitosis**: Mitosis is a type of cell division where a single parent cell divides to produce two identical daughter cells. Both the parent and daughter cells are diploid (2N), meaning they contain two sets of chromosomes.

2. **Identifying Ploidy**: In the context of cell division:
- "2N" represents a diploid cell (having two sets of chromosomes).
- "N" represents a haploid cell (having one set of chromosomes).

3. **Analyzing the Options**: The question provides several options that represent different ploidy states:
- **Option 1: 2N - 2N**: This indicates that both the parent cell and the daughter cells are diploid. This is characteristic of mitosis.
- **Option 2: 2N - N**: This indicates that the parent cell is diploid, but the daughter cell is haploid. This is characteristic of meiosis, not mitosis.
- **Option 3: 2N - N**: This is the same as Option 2 and also represents meiosis.

4. **Conclusion**: The correct symbol that represents mitotic cell division is **2N - 2N**, as it shows that both the parent and daughter cells are diploid.

### Final Answer:
The symbol that represents mitotic cell division is **2N - 2N**.
