The Cell Cycle Components of the Cell Cycle The Cell Cycle We have already discussed how the two main events of cellular reproduction are the copying of cellular components and the cleavage of the cell. These two events, copying and cleaving, represent the two larger phases of the cell cycle, interphase and Mitosis. Mitosis is the part of the cell cycle when the cell prepares for and completes cell division. During interphase, appropriate cellular components are copied. Interphase is also a time of checkpoints to make sure that the cell is ready to proceed into mitosis. Both of these two phases have further sub-divisions. Since the cell cycle is a "cycle" it has no distinct beginning or ending. Cells are continually entering and exiting the various phases of the cycle. Mitosis will be covered in depth in the; here we will focus on what goes on during interphase. Interphase Figure %: Interphase and Mitosis Interphase
