Mitosis, the process of cell division, occurs during the M phase of the cell cycle and includes stages such as prophase, metaphase, anaphase, and telophase.
Cell division occurs in the M phase, which is the phase of the cell cycle where mitosis and cytokinesis take place, resulting in the division of the cell into two daughter cells.
(1) S phase:
The S phase is when DNA replication occurs, but cell division does not take place during this phase.
(2) G₁ phase:
The G₁ phase is a growth phase where the cell prepares for DNA replication but does not involve cell division.
(3) G₂ phase:
The G₂ phase is a growth phase where the cell prepares for mitosis, but cell division does not occur here.
(4) M phase:
This is the correct answer. The M phase is where cell division occurs through mitosis and cytokinesis.
Conclusion:
The correct answer is Option 4: M phase as it is the phase of the cell cycle where cell division occurs.
