The Cell Cycle

Cells undergo a regular cycle of growth and division.The Cell undergoes a repeated cycle of interphase, mitosis and cytokinesis.The cell cycles for different cells have different lengths.Some cells replicate often others do not replicate or have a very long cell cycle.The more differentiated the cell, the longer the cell cycle.During Interphase the cell grows and carries out its normal functions and DNA is replicated.The cell continues to increases in size and synthesise proteins and mitochondria replicate.Nuclear division (mitosis) then takes place followed by cytokinesis which produces two separate cells.The cell enters the G₀ phase when it leaves the cell cycle temporarily or permanently because of damage, senescence or differentiation.
