Here's a breakdown:

* Mitosis: The process of cell division that produces two identical daughter cells.

* Anaphase: One of the four main stages of mitosis. It's characterized by the separation of sister chromatids (identical copies of a chromosome) and their movement towards opposite poles of the cell.

What happens during Anaphase:

1. Centromeres split: The centromere, which holds the sister chromatids together, divides.

2. Chromatids separate: The sister chromatids are now considered individual chromosomes and are pulled apart by spindle fibers.

3. Movement to poles: The chromosomes move towards opposite poles of the cell, guided by the spindle fibers.

4. Cell elongation: The cell starts to elongate as the poles move further apart.

Overall, anaphase is a crucial step in mitosis, ensuring that each daughter cell receives a complete and identical set of chromosomes.
