Mitosis Description

Mitosis--which is a continuous process occurring in five stages: prophase, prometaphase, metaphase, anaphase, and telophase--is the division of the nucleus. During prophase, chan ... begins to form in cytoplasm (it is made of microtubules radiating from two centrosomes). Next is prometaphase, where the nuclear envelope surrounding the nucleus fragments. Bundles of microtubules ext ... from each pole toward middle of cell. Kinetochore develops in centromere region of chromosomes. In metaphase, centrosomes are at opposite ends of the poles of the cell; the chromosomes meet on the me ...
