Motor MAPs and microtubules interact to create the movements that are seen during mitosis.

Motor MAPs use energy from ATP to pull or push the microtubules. Microtubules, which start at the microtubule organizing centers (MTOC's) or centrioles, polymerize (lengthen) or de-polymerize (shorten) as necessary.

The result of the interaction of these elements is that the centrioles move to opposite poles of the cell, sister chromotids separate and move to the poles, and the cell elongates.
