Web2 days ago · Furthermore, the cell cycle plays a crucial role in the repair of damaged tissues. For example, after injury or wound, cells divide to replace damaged cells and allow tissue to regenerate. The ability of cells to enter the cell cycle and divide is critical to the recovery and healing of the body. However, faulty regulation of the cell cycle can ... WebIn a simple manner, the cell cycle is the time that elapses since the cell divides until it re-enters in another mitotic division. The cell cycle is divided into different phases, named G1 (gap phase 1), S (DNA synthesis), G2 (gap phase 2) and M (mitosis/meiosis), eventually resulting in the formation of two daughter cells.
