Answer:

Introduction:
The cell cycle is the process by which a cell grows, duplicates its genetic material, and divides into two identical daughter cells. The cell cycle is divided into two main phases: interphase and M phase. Interphase is the period between cell divisions, whereas M phase is the period of cell division. M phase is further divided into four stages: prophase, metaphase, anaphase, and telophase. The final stages of M phase are karyokinesis and cytokinesis.

Karyokinesis:
Karyokinesis is the process of separating the duplicated chromosomes into two identical sets. This process occurs during the later stages of mitosis and is essential for the formation of two identical daughter cells. During karyokinesis, the chromosomes condense and line up along the cell's equator. The spindle fibers then pull the chromosomes apart, separating them into two sets.

Cytokinesis:
Cytokinesis is the process of dividing the cytoplasm, organelles, and other cellular components into two daughter cells. Cytokinesis begins during the later stages of mitosis and is completed shortly after the end of telophase. During cytokinesis, a contractile ring of actin and myosin filaments forms around the cell's equator. This ring contracts, pinching the cell in two and forming two identical daughter cells.

Telophase:
Telophase is the final stage of mitosis, and it marks the end of M phase. During telophase, the nuclear envelope reforms around each set of separated chromosomes, and the spindle fibers disappear. The chromosomes begin to decondense, and the nucleolus reappears. The cell is now ready to enter interphase, the period of growth and preparation for the next cell division.

Conclusion:
In conclusion, telophase marks the end of M phase, the period of cell division. During telophase, the nuclear envelope reforms, the spindle fibers disappear, and the chromosomes begin to decondense. The cell is now ready to enter interphase and prepare for the next cell division.

Most of the organelle duplication also occurs during this phase. S phasemarks the phase of DNA replication and chromosome duplication. G2 phase is the period of cytoplasmic growth. Mitosis is also divided into four stages namely prophase,metaphase, anaphase and telophase.
