In prophase of mitosis, strains of chromosomes begin to condense and become visible.
00:09
The nucleoli disappear.
00:11
Spindle fibers begin to form in the cytoplasm, extending from one centrosome to the other.
00:17
Centrioles begin to migrate to the poles, and the nuclear membrane begins to disintegrate.
00:26
During metaphase, chromosomes line up on the equator, or the metaphase plate.
00:31
Chromosomes are at opposite poles of the cell, and spindle fibers run from centrosomes to the centromeres of the chromosomes.
00:44
During anaphase, the centromeres of each chromosomes separate, and spindle fibers begin to pull the sister chromosomes apart.
00:54
Anaphase is also the shortest phase of mitosis...
