Cell Cycle

Why is the Cell Cycle often represented as a circle?

• Because it is easy to draw

• Because cell cycles has a distinct beginning and end point

• to highlight the checkpoints

• to show that it repeats over and over

• G0

• G1

• S

• G2

During which stage of the cell cycle does the nucleus divide?

• interphase

• mitosis

• endocytosis

• cytokinesis
