When The cell cycle begins again after?

The cell cycle begins again after the completion of mitosis, specifically following the final stage known as cytokinesis, where the cytoplasm of the parent cell divides, resulting in two daughter cells. Each daughter cell then enters the interphase phase, where it prepares for the next round of division. Interphase consists of three stages: G1 (growth), S (DNA synthesis), and G2 (preparation for mitosis). Once interphase is complete, the cell is ready to enter mitosis again, thus restarting the cycle.
