Summary Introduction

To determine:

The three examples of checkpoints that the cell monitors before proceeding through the cell cycle.

Introduction:

The cell division cycle is the events that take place in a cell that leads to the division and duplication of cellular DNA into two daughter cells. The cell cycle has four phases: ${\text{G}}_{\text{1}}$ phase, S phase, ${\text{G}}_2$ phase and M phase. All cells pass through these phases to divide into two.

A cell cycle is regulated at different check points that prevents uncontrolled cell division and detects the damage in genetic material. Checkpoints halt the progression of cell to the next phase of cell cycle until the DNA damaged has been repaired.
