The Cell cycle is the process in which a eukaryotic cell divides itself into two cells. It includes the preparation that have to take place inside of the cell before it can divide itself. Between different species and cell types the duration can vary greatly.
Phases
M-Phase
During the M-Phase the cell first splits the nucleus in the mitosis. Afterwards the cytoplasm divides in the cytokinesis. The M-Phase takes normally around one hour.
Interphase
The cell grows during the interface to get big enough to divide again. It's also the time during which the cell has to synthesize proteins and do it's job in the organism.
-Phase
At the end of the -Phase the cell controls whether it's DNA is damaged and whether the vicinity of the cell is favorable for cell proliferation. If those conditions are met the cell enter the S-Phase.
S-Phase
During the S-Phase each chromosome of the DNA gets duplicated.
