The Cell Cycle




1. Interphase: (comes before mitosis)

Before the cell can enter division, it must prepare itself by replicating all
its genetic information and organelles. Interphase proceeds in four stages;
G0, G1, S, and G2.

G0 phase: When the cell leaves the cell cycle and quit dividing. It can…

Stages of Mitosis:

2. Prophase

The chromosomes condense, getting shorter and fatter. The
centrioles begin moving to opposite ends of the cell, forming and
network of protein fibres across it called a spindle. The nuclear
envelope breaks down and lies free in the cytoplasm.




3. Metaphase

The chromosomes (each with…

The centromeres divide, separating each pair of sister chromatids.
The spindles contract, pulling chromatids to opposite ends of the
cell, centromeres first.




5. Telophase

The chromatids reach the opposite poles of the spindle. They uncoil
and become long and thin again ­ they are now called chromosomes
again.
A nuclear…
