Sister chromatits line up along the equatorial plane. Spindle fibers extend from centromere to the poles.

The briefest of the phases- involves sister chromatids of each chromosome seperating and moving to opposite poles.

Chromosomes become grainy. Spindle fibers dissolve, become new neuclear envelope. Protoplasm gets trapped between cell plate.
