Select the correct match

Options

A. Reformation of ER and golgi complex - Telophase
B. Invisible phase of cell cycle - Metaphase
C. Polar movement of chromatids - S-phase
D. Recombination nodules formation - Zygotene

Answer

To solve the question "Select the correct match", we will analyze each option provided and determine which one is accurate.

**Step 1: Analyze Option A**
- **Statement**: Reformation of ER and Golgi complex occurs at telophase.
- **Explanation**: During telophase, the nuclear envelope reforms, and the endoplasmic reticulum (ER) and Golgi apparatus also reassemble. This is a crucial part of the cell cycle as the cell prepares to divide into two daughter cells.
- **Conclusion**: This statement is correct.

**Step 2: Analyze Option B**
- **Statement**: Invisible phase of cell cycle is called metaphase.
- **Explanation**: The invisible phase of the cell cycle is actually the S phase (Synthesis phase), during which DNA is replicated, and the chromosomes are not yet visible. In contrast, during metaphase, chromosomes are clearly visible as they align in the center of the cell.
- **Conclusion**: This statement is incorrect.

**Step 3: Analyze Option C**
- **Statement**: Polar movement of chromatids occurs in S phase.
- **Explanation**: The S phase is primarily focused on DNA replication. The polar movement of chromatids occurs during anaphase, when the sister chromatids are pulled apart to opposite poles of the cell.
- **Conclusion**: This statement is incorrect.

**Step 4: Analyze Option D**
- **Statement**: Recombination nodules formation occurs at zygotene phase.
- **Explanation**: The zygotene phase is part of prophase I of meiosis, where homologous chromosomes begin to pair. However, the actual formation of recombination nodules occurs during the pachytene stage, not zygotene.
- **Conclusion**: This statement is incorrect.

**Final Conclusion**
After analyzing all options, the only correct match is **Option A**: Reformation of ER and Golgi complex occurs at telophase.
