The Cell Cycle Runs in a Fixed Order: Interphase Then M Phase

Definition

Cell cycle

The cell cycle is a series of stages that a cell goes through to grow, replicate its DNA, and divide into two daughter cells.

The cell cycle is the repeating sequence of events a cell passes through from one division to the next.
It has two parts: a long interphase followed by a short M phase.
During interphase the cell grows and copies its DNA ready to divide.
During M phase the cell divides into two, made up of mitosis and cytokinesis.

Note

The order is always the same and the cycle repeats each time a cell divides.
A cell that stops dividing leaves the cycle and rests in a state called G0.

Interphase Is Split Into Three Stages: G1, S and G2

Interphase is the longest part of the cell cycle.
It runs in the fixed order G1, then S, then G2.
G1 Phase (First Gap)
