Anaphase

See

The onset of anaphase is triggered by specific biochemical changes that occur to regulate the division cycle through modulation of the enzyme cascade responsible for cell-wide protein phosphorylation.
Faithful anaphase is ensured by Mis4, a sister chromatid cohesion molecule required in S phase and not destroyed in G1 phase.
The motor for poleward chromosome movement in anaphase is in or near the kinetochore.
Anaphase is preceded by metaphase, by the end of which fully condensed sister chromatids are arranged in pairs in the spindle midzone, defining a structure referred to as the metaphase plate.
All the chromosomes are able to coordinate the breaking of their centromeres quite well and the speed at which the chromatids move is impressive so anaphase is a sight to see! (In a living cell, of course.
