Final answer:
Cytokinesis is completed in the cell cycle during Telophase after the stages of mitosis are concluded.
Step-by-step explanation:
Cytokinesis is completed in the cell cycle as the next cycle begins during Telophase. Once interphase is over, a cell enters the stages of mitosis which consist of prophase, metaphase, anaphase and telophase. Cytokinesis the division of the cytoplasm into two new cells follows after telophase.
This process is essential for cell division in all dividing eukaryotic cells except for germ cells involved in reproductive processes. The correct answer to which phase cytokinesis is completed as the next cycle begins is C. In Telophase.
