Which statement is not true about mitosis?

Options

A. Mitosis is a process that duplicates and divides the nuclear contents only
B. Mitosis produces two daughter cells that contain the same number of chromosomes as the parent cell
C. Mitosis produces two daughter cells that contain the same kinds of chromosomes as the parent cell
D. Mitosis uses a diploid parent cell to form daughter cells containing n chromosomes

Answer

To determine which statement is not true about mitosis, we will analyze each statement one by one.

### Step-by-Step Solution:

1. **Analyze Statement 1**: "Mitosis is a process that duplicates and divides the nuclear contents only."
- This statement is incorrect. Mitosis does not only duplicate and divide the nuclear contents; it also involves the duplication and division of the entire cell contents, including cytoplasm and organelles. Therefore, this statement is not true.

2. **Analyze Statement 2**: "Mitosis produces two daughter cells that contain the same number of chromosomes as the parent cell."
- This statement is correct. Mitosis results in two daughter cells that each have the same number of chromosomes as the parent cell. If the parent cell is diploid (2n), the daughter cells will also be diploid (2n).

3. **Analyze Statement 3**: "Mitosis produces two daughter cells that contain the same kinds of chromosomes as the parent cell."
- This statement is also correct. The daughter cells produced through mitosis are identical to the parent cell, meaning they contain the same types of chromosomes.

4. **Analyze Statement 4**: "Mitosis uses a diploid parent cell to form daughter cells containing n chromosomes."
- This statement is incorrect. In mitosis, a diploid parent cell (2n) divides to produce daughter cells that also have 2n chromosomes, not n chromosomes. Therefore, this statement is also not true.

### Conclusion:
The statements that are not true about mitosis are Statement 1 and Statement 4.

### Final Answer:
The statement that is not true about mitosis is: "Mitosis is a process that duplicates and divides the nuclear contents only." (Statement 1) and "Mitosis uses a diploid parent cell to form daughter cells containing n chromosomes." (Statement 4).
