Summary Introduction
Introduction:
Cell division is an important mechanism in living cells; the purpose of cell division is reproduction and damage repair (regeneration). Before the initiation of cell division, genetic material (chromosomes) is already duplicated; at the time of cell division, this genetic material is equally distributed to daughter cells. This equal distribution of chromosomes is facilitated by microtubules (Hollow tubes), through separation chromosomes in anaphase of mitosis. There are three types of microtubules that take part in the separation process- these are - aster microtubules, polar microtubules, and kinetochore microtubules.
