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 determine which of the listed events are parts of mitosis, we will analyze each option one by one.

### Step-by-Step Solution:

1. **Identify the events:**
- The events listed are:
- I. Interphase
- II. Anaphase
- III. Cytokinesis

2. **Analyze Interphase:**
- Interphase is the phase of the cell cycle where the cell prepares for mitosis. It consists of three sub-phases: G1 (cell growth), S (DNA replication), and G2 (preparation for mitosis).
- **Conclusion:** Interphase is **not** a part of mitosis.

3. **Analyze Anaphase:**
- Anaphase is a specific stage of mitosis where the sister chromatids are pulled apart and move towards opposite poles of the cell. This is a crucial step in ensuring that each daughter cell receives an identical set of chromosomes.
- **Conclusion:** Anaphase **is** a part of mitosis.

4. **Analyze Cytokinesis:**
- Cytokinesis is the process that follows mitosis and involves the division of the cytoplasm, resulting in two separate daughter cells. While it occurs after mitosis, it is not considered a part of mitosis itself.
- **Conclusion:** Cytokinesis is **not** a part of mitosis.

5. **Summarize the findings:**
- From the analysis:
- I. Interphase - Not part of mitosis
- II. Anaphase - Part of mitosis
- III. Cytokinesis - Not part of mitosis

6. **Final Answer:**
- The only event that is part of mitosis is **Anaphase** (II).
