Mitosis is the second & shortest stage of the cell cycle.
Good now how about these questions... Why is cell division important? How many cells are made? What is inside the nucleus? And finally... What stage of mitosis do the chromosomes line up?
Cell division is important because it helps humans reproduce themselves. There are two cells in mitosis. Inside of the nucleus is a fully enclosed nuclear membrane it contains the majority of the cells genetic material. Metaphase. Chromosomes line up at the metaphase plate, under tension from the mitotic spindle.
