Mitosis

Mitosis (normal cell division)

Chromosomes replicate BEFORE division. Next comes mitosis:  Chromosomes appear and nucleus disappears.  Chromosomes line-up in center of cell (equator).  Chromosomes are divided to opposite ends of cell (poles).  Two nuclei form. Rest of cell divides.

How many chromosomes are in each cell? Two Same as original. (For humans the number is 46) 4 in this diagram! How many cells are created?

Cells produced by mitosis will
