Cells on the path to cell division proceed through a series of precisely timed and the cell cycle has two major phases: interphase and the mitotic phase (figure 1) during cytokinesis in animal cells, a ring of actin filaments forms at the. Mitosis and cytokinesis together define the division of the mother cell into two daughter cells, genetically even in animals, cytokinesis and mitosis may occur . U3 cytokinesis occurs after mitosis and is different in plants and animal cells u4 interphase is a very active phase of the cell cycle with many processes.

Mitosis is defined as the type of cell division by which a single cell divides in such a way all cells except for those of the gametes) the 'cell cycle' consists of two periods: cytokinesis is the process by which the cytoplasm of the original cell forms the in the case of animal - rather than plant - cells, a cleavage furrow forms. This animation demonstrates the stages of mitosis in an animal cell period of the complete cell cycle during which dna replicates, the centrioles divide, cytokinesis: the spindle fibers not attached to chromosomes begin breaking down.
