Which of these events are parts of mitosis ?
I. Interphase
II. Anaphase
III. Cytokinesis

Options

A. I , II and III
B. I and III only
C. I only
D. II only

Answer

To solve the question of which events are parts of mitosis, we need to analyze each of the given options: Interphase, Anaphase, and Cytokinesis.

### Step-by-Step Solution:

1. **Understanding Mitosis**:
- Mitosis is a type of cell division that results in two genetically identical daughter cells. It is also known as equational division because the chromosome number remains the same before and after division.

2. **Phases of Mitosis**:
- Mitosis consists of four main phases:
- Prophase
- Metaphase
- Anaphase
- Telophase

3. **Evaluating the Options**:
- **Option I: Interphase**:
- Interphase is not a part of mitosis. It is the phase where the cell prepares for division and is divided into three sub-phases: G1 (Gap 1), S (Synthesis), and G2 (Gap 2). Therefore, this option is incorrect.

- **Option II: Anaphase**:
- Anaphase is indeed one of the phases of mitosis. During this phase, the sister chromatids are pulled apart to opposite poles of the cell. Thus, this option is correct.

- **Option III: Cytokinesis**:
- Cytokinesis is the process that follows mitosis, where the cytoplasm of the parent cell divides to form two daughter cells. However, it is not considered a part of mitosis itself. Therefore, this option is also incorrect.

4. **Conclusion**:
- Based on the analysis, the only event that is part of mitosis is Anaphase. Therefore, the correct answer to the question is **II only**.

### Final Answer:
The correct answer is **II. Anaphase**.
