The cell cycle is the series of events that take place in a cell that causes it to divide into two daughter cells. The cell cycle is a process through which cells replicate and make two new cells. It has different stages called G1, S, G2, and M. The cell cycle can be thought of as the life cycle of a cell, and it is the series of growth and development steps a cell undergoes between its “birth”—formation by the division of a mother cell—and reproduction—division to make two new daughter cells.
The eukaryotic cell cycle consists of four distinct phases: G1 phase, S phase (synthesis), G2 phase (collectively known as interphase) and M phase (mitosis and cytokinesis) . During interphase, the cell grows, accumulates nutrients needed for mitosis, and replicates its DNA and some of its organelles. During the M phase, the replicated chromosomes, organelles, and cytoplasm separate into two new daughter cells.
The cell cycle is regulated by checkpoints that ensure that the cell is ready to proceed to the next stage. If the cell doesnt meet the requirements of the checkpoint, it may pause until it can fix the issue. The cell cycle is essential for the growth and development of multicellular organisms, and it is also the process by which hair, skin, blood cells, and some internal organs are regenerated and healed.
