Verified step by step guidance

Understand the cell cycle phases: The cell cycle consists of interphase (G1, S, G2) and the M phase (mitosis). The M phase is where cell division occurs.
Recognize the events of the M phase: During mitosis, the cell undergoes several stages including prophase, metaphase, anaphase, and telophase, leading to the division of the nucleus.
Identify the end of the M phase: The final step of the M phase is cytokinesis, where the cytoplasm divides, resulting in two separate daughter cells.
Clarify the transition to G1 phase: After cytokinesis, the cell enters the G1 phase, where it begins to grow and perform normal functions, preparing for the next cycle.
Summarize the outcome: At the end of the M phase, cell division is completed, resulting in two genetically identical daughter cells, ready to enter the G1 phase.
