Which is not the character of mitosis

Options

A. Leptotene
B. Zygotene
C. Pachytene
D. All the above

Answer

To determine which option is not a character of mitosis, we need to analyze the options provided and understand the characteristics of both mitosis and meiosis.

### Step-by-Step Solution:

1. **Understand Mitosis**:
- Mitosis is a type of cell division that results in two daughter cells, each having the same number of chromosomes as the parent cell. It is known as an equational division.

2. **Identify the Stages of Mitosis**:
- Mitosis consists of four main stages:
- **Prophase**
- **Metaphase**
- **Anaphase**
- **Telophase**

3. **Understand Meiosis**:
- Meiosis is a different type of cell division that reduces the chromosome number by half, resulting in four daughter cells. It consists of two rounds of division: Meiosis I and Meiosis II.

4. **Identify Stages of Meiosis**:
- The first stage of Meiosis I is Prophase I, which has several sub-stages:
- **Leptotene**
- **Zygotene**
- **Pachytene**
- **Diplotene**
- **Diakinesis**
- The stages Leptotene, Zygotene, and Pachytene are specific to meiosis and do not occur in mitosis.

5. **Analyze the Options**:
- Option 1: Leptotene (meiosis)
- Option 2: Zygotene (meiosis)
- Option 3: Pachytene (meiosis)
- Option 4: All the above (none belong to mitosis)

6. **Conclusion**:
- Since all the listed options (Leptotene, Zygotene, and Pachytene) are stages of meiosis and do not occur in mitosis, the correct answer is:
- **All the above (Option 4)**.

### Final Answer:
**All the above (Option 4)** is not a character of mitosis.
