Select the CORRECT statement related to mitosis

Options

A. Amount of DNA in the parent cell is first halved and then distributed into two daughter cells
B. Amount of DNA in the parent cell is first doubled and then distributed into two daughter cells
C. Amount of DNA in the parent cell is first halved and then distributed into four daughter cells
D. Amount of DNA in the parent cell is first doubled and then distributed into four daughter cells

Answer

To determine the correct statement related to mitosis, let's analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding Mitosis**: Mitosis is a type of cell division that results in two daughter cells, each genetically identical to the parent cell. The process involves the duplication of DNA.

2. **Analyzing Option 1**:
- Statement: "The DNA amount is first half in the parent cell and then it will be divided into two daughter cells."
- Evaluation: This statement is incorrect because the DNA amount in the parent cell is not half; it is at full capacity (2N) before division.

3. **Analyzing Option 2**:
- Statement: "The amount of DNA in the parent cell is first half in the parent cell and then it is divided into two daughter cells."
- Evaluation: This statement is misleading. The DNA in the parent cell is not half; it is doubled during the S phase before mitosis begins. Therefore, this option is incorrect.

4. **Analyzing Option 3**:
- Statement: "The amount of DNA in the parent cell is first half and then it is divided into four daughter cells."
- Evaluation: This statement is incorrect. In mitosis, the DNA does not become half; it is duplicated and results in two daughter cells, not four.

5. **Analyzing Option 4**:
- Statement: "The amount of DNA in the parent cell is first doubled twice and then it is distributed into the four daughter cells."
- Evaluation: This statement is also incorrect. In mitosis, DNA is doubled once during the S phase and then divided into two daughter cells, not four.

6. **Conclusion**: After analyzing all options, it is clear that none of the provided statements correctly describe the process of mitosis. However, the closest correct interpretation aligns with the understanding that DNA is doubled during the S phase and then divided into two daughter cells during mitosis.

### Correct Answer:
None of the options are correct as stated. However, the correct understanding is that the DNA is doubled in the parent cell and then divided into two daughter cells.
