During prophase in mitosis, the nuclear membrane breaks down and chromatin condenses. During prophase one of meiosis, the chromosomes group together and crossing over occurs. During prophase two, the chromosomes condense and are attached to spindle fibers where they can be moved.
During anaphase, the sister chromatids split apart and move from the cell's equator (metaphase plate) to the poles of the cell. The kinetochore is attached to the centromere.
During mitosis, the chromosomes align in the middle of the cell, with the sister chromatids of each chromosome on either side of the metaphase plate.
Telophase is technically the final stage of mitosis. Its name derives from the latin word telos which means end. During this phase, the sister chromatids reach opposite poles.

hope it helps then plz mark as brainliest

➡️Metaphase and Anaphase. The next two major events that take place in mitosis are the alignment of chromosomes at the center of the cell and the subsequent separation of sister chromatids to opposite mitotic spindle poles. These two events occur in metaphase and anaphase, respectively.
