Answer 2

Cell cycle checkpoints are surveillance mechanisms that monitor the order, integrity and fidelity of the major events of the cell cycle.

Explanation:

• These include growth to the appropriate cell size,replication and integrity of the chromosomes and their accurate segregation at mitosis.
• Different cell cycle checkpoints have evolved that prevent replication of damaged DNA and premature entry to or exit from mitosis and allow time for DNA repair after encountering DNA damage.
• The main cell cycle checkpoints are the G1/S checkpoint, the intra-S checkpoint and the G2/M checkpoint [60].
• The cell cycle of stage process in which the cell increases in size (gap 1 or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2 or G2, stage) and divides (mitosis or M, stage).
• The stages G1, S, and G2 make up interphase which accounts for the span between cell divisions.
• In eukaryotes the cell cycle consists of four discrete phases: G1, S, G2, and M.
• The S or synthesis phase is when DNA replication occurs and the M or mitosis phase is when the cell actually divides.The other two phases  G1 and G2 the so called gap phases are less dramatic but equally important.
