Between which two cell cycle stages does karyokinesis lie ?

Options

A. `G_(2)` and cytokinesis
B. Cytokinesis and `G_(0)`
C. `G_(0) and G_(1)`
D. `G_(1) and G_(2)`

Answer

To determine between which two cell cycle stages karyokinesis occurs, we need to understand the cell cycle and the specific phases involved.

### Step-by-Step Solution:

1. **Understanding Karyokinesis**:
- Karyokinesis refers to the process of nuclear division during cell division. It is a crucial part of mitosis.

2. **Identifying the Cell Cycle Stages**:
- The cell cycle consists of several stages:
- G1 phase (Gap 1)
- S phase (Synthesis)
- G2 phase (Gap 2)
- M phase (Mitosis)
- Cytokinesis

3. **Locating Karyokinesis**:
- Karyokinesis occurs during the M phase of the cell cycle, which is specifically the phase where mitosis takes place.

4. **Understanding the Relationship with Other Phases**:
- Karyokinesis is followed by cytokinesis, which is the division of the cytoplasm.
- Therefore, karyokinesis lies between the G2 phase (the phase just before mitosis) and cytokinesis (the phase that follows karyokinesis).

5. **Conclusion**:
- Karyokinesis occurs between the G2 phase and the cytokinesis phase.

### Final Answer:
Karyokinesis lies between the G2 phase and the cytokinesis phase.
