Which phase of mitosis is characterized by the chromosomes attaching to spindle fibers and aligning in the middle of the cell?

The phase of mitosis characterized by chromosomes attaching to spindle fibers and aligning in the middle of the cell is called metaphase. During this stage, the chromosomes, which have already been replicated and condensed, line up along the metaphase plate, ensuring that each sister chromatid will be equally distributed to the daughter cells during the subsequent phase, anaphase.
