This is interphase, this is the longest phase of the cell cycle. Interphase is when the cell grows and is a stringy substance.

Early Prophase: Spindle Fibers form after the nucleolus disappears.

Late Prophase: The spindle fibers start attaching to the centromeres. The nuclear membrane disappears, the spindle fibres attach to the chromosomes.

Metaphase: all the chromosomes move towards the middle of the cell. (equator)

Anaphase: the spindle fibres start to pull the sister chromatids to opposite sides of the pole

Telophase: One complete set of chromosomes is at each pole of the cell. A nuclear membrane forms around each set. Then the nucleolus forms and the cell is ready to divide.

Cytokinesis: The final stage of the cell cycle and divides the 2 nuclei into 2 daughter cells.

That is how mitosis and the cell cycle work.
