The
cell cycle, or cell-division cycle, is the series of events that take
place in a cell leading to its division and duplication (replication).
In cells without a nucleus (prokaryotic), the cell cycle occurs via a
process termed binary fission.In cells with a nucleus
(eukaryotes), the cell cycle can be divided in two periods:
interphase—during which the cell grows, accumulating nutrients
needed for mitosis and duplicating its DNA—and the mitotic (M) phase,
during which the cell splits itself into two distinct cells, often
called "daughter cells" and the final phase, cytokinesis, where the new
cell is completely divided. The cell-division cycle is a vital process
by which a single-celled fertilized egg develops into a mature organism,
as well as the process by which hair, skin, blood cells, and some
internal organs are renewed.
