The stage of mitosis cell division



Cell division: Cell division is the process, which cells multiply by continuous series for growth and repair of tissue.
Stage of mitosis: Mitosis is divided into 5 stages-
1.     Prophase
2.     Pro-metaphase
3.     Metaphase
4.     Anaphase
5.     Telophase
Prophase: Each chromosome splits into two chromatids at its centromere. Paired centroiles are separated from each other. Subsequently nuclear membrane disintegastes and the nucleolus disappears.
Pro-Metaphase: It is the second phase of mitosis. Nuclear membrane and nucleolus disappear. Protein made two made two poled spindle apparatus is obvious, There are two fibre in spindle apparatus. Spindle fibre-prolonged one to another pole, Chromosomal fibre-Attach with centromere of chromosome.
Metaphase: The centromere of each chromosomes organize them selves along the microtubules of the mitotic spindles.
Anaphase: Centromere splists longitudinally and two chromatids migrate to the opposite pole of mitotiespindle.
Telophase: The new daughter chromosomes becomes covered by new nuclear membrane. Finally cytoplasm divides and the two complete new cells are fromed.
