The Cell Cycle: Interphase and the Mitotic Phase
Captions available
The idea
The cell cycle runs from one parent cell to two identical daughters, split into interphase, when the cell grows and copies its DNA, and the mitotic phase, when that DNA separates.
In practice
A cell spends most of the cycle in interphase, entering the brief mitotic phase once preparation is complete.
Where people slip
Interphase is active preparation, not rest — the cell stays biochemically busy throughout.
