longest period of cell cycle in which DNA replicates, the centrioles divide, and proteins are actively produced
Nucleolus fades and chromatin condenses into chromosomes. Each replicated chromosome comprises two chromatids, both with the same genetic information. Microtubules of the cytoskeleton, responsible for cell shape, motility and attachment to other cells during interphase, disassemble. And the building blocks of these microtubules are used to grow the mitotic spindle from the region of the centrosomes.
Tension applied by the spindle fibers aligns all chromosomes in one plane at the center of the cell.
Spindle fibers shorten, the kinetochores separate, and the chromatids (daughter chromosomes) are pulled apart and begin moving to the cell poles
The daughter chromosomes arrive at the poles and the spindle fibers that have pulled them apart disappear.
The spindle fibers not attached to chromosomes begin breaking down until only that portion of overlap is left. It is in this region that a contractile ring cleaves the cell into two daughter cells. Microtubules then reorganize into a new cytoskeleton for the return to interphase
