During mitosis, what are the opposite ends of a cell where chromatids migrate called?

In mitosis, the terms used to describe the areas where chromatids migrate are referred to as poles. During this process, the cell prepares to divide, and the chromosomes, which have been replicated, align at the center of the cell. The spindle fibers, which are formed by microtubules, pull the sister chromatids apart towards opposite ends of the cell, known as the poles. As the cell progresses through anaphase, the chromatids are separated and are drawn towards these poles, ensuring that each new daughter cell will receive an identical set of chromosomes.

While centromeres are the regions of the chromosome where the sister chromatids are joined, they do not refer to the opposite ends of the cell. Spindles denote the structure that facilitates the movement of chromatids but do not define the areas themselves where this movement occurs. The cytoplasm is the gel-like substance within the cell and is not specifically related to the migration of chromatids during mitosis. Therefore, the term "poles" accurately describes the distinct regions of the cell where chromatids move during division.
