Normal life processes,at the end DNA duplicates

Nuclear membrane and nucleolus disappear,chromosomes,centrioles, & spindle fibers form.

Metaphase

. 

Chromosomes line up along the middle & attach to spindle fibers. 

Anaphase

Chromosomes arepulled to opposite endsof the cell by shortening spindle fibers

Chromosomes uncoil, nuclear membrane forms.

Cytoplasm separates, cell membrane pinches into two new daughter cells.
