Which is the character of mitosis ?

Options

A. Leptotene
B. Zygotene
C. Pachytene
D. None of the above

Answer

**Step-by-Step Solution:**

1. **Understanding 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. This process is essential for growth, repair, and asexual reproduction in organisms.

2. **Identifying the Options**: The options given are Leptotene, Zygotene, Pachytene, and none of the above. These terms refer to specific stages in meiosis, not mitosis.

3. **Analyzing the Stages**:
- **Leptotene**: This is the first stage of prophase I in meiosis where chromatin condenses into visible chromosomes.
- **Zygotene**: This is the second stage of prophase I in meiosis where homologous chromosomes begin to pair up and form a synaptonemal complex.
- **Pachytene**: This is the third stage of prophase I in meiosis where bivalents (tetrads) are formed.

4. **Recognizing the Key Characteristic of Mitosis**: Mitosis is characterized as an equational division, meaning that the chromosome number in the daughter cells remains the same as in the parent cell.

5. **Conclusion**: Since all the options (Leptotene, Zygotene, Pachytene) are stages of meiosis and not mitosis, the correct answer to the question "Which is the character of mitosis?" is "none of the above."

**Final Answer**: None of the above.
