Cell cycle checkpoints are control mechanisms in eukaryotic cells which ensure proper division of the cell. The Cell Cycle consists of three checkpoints. These checkpoints are the G1 checkpoint, the G2 checkpoint, and the M checkpoint. These checkpoints all have different functions. Cells have many different mechanisms to restrict cell division, repair DNA damage, and prevent the development of cancer. Cancers are formed as cells acquire a series of mutations, or changes in DNA, that make them divide more quickly, escape internal and external controls on division, and avoid programmed cell death. The cell cycle is divided into three parts, Interphase,M phase, and Cytokinesis. The first part of the cell cycle starts out with interphase, the
