Mitosis- the division of the nucleus.
Name the stages and what happens in each stage.
Interphase: the period between active division when the cells DNA is doubled.
Prophase: begins with the shortening of the chroosomes and ends with the dissolution of the nucleolus and the breakdown of the nuclear membrane.
Metaphase: the alignment of the chromosomes on the cell equator and the attaching of the spindle fibers to the kinetochores.
Anaphase: the centromeres divide and the chromosomes move to the poles.
Telophase: the chromosomes reach the poles and begin to relax. The nuclear membrane reforms as do the nucleoli.
