Anaphase is the stage of cell division in which the sister chromatids separate and move towards opposite ends (poles) of the cell. This occurs in both mitosis and meiosis.
During anaphase, the microtubules of the mitotic spindle, known as the kinetochore microtubules, shorten and pull the sister chromatids apart. The chromatids are then referred to as daughter chromosomes.
In mitosis, anaphase follows the metaphase stage, during which the chromosomes align at the center of the cell. In meiosis, anaphase I is the stage where the pairs of homologous chromosomes separate, while anaphase II is when the sister chromatids separate.
Anaphase is a crucial stage in ensuring the accurate distribution of genetic material to the resulting daughter cells. The movement of chromosomes towards opposite poles ensures that each daughter cell receives a complete set of chromosomes.
Overall, anaphase is a highly coordinated and dynamic process that plays a vital role in cell division and genetic stability.
