WebThe chromosomes align themselves along the metaphase plate of the spindle apparatus. Anaphase The shortest stage of mitosis. The centromeres divide, and the sister chromatids of each chromosome are pulled apart - or 'disjoin' - and move to the opposite ends of the cell, pulled by spindle fibres attached to the kinetochore regions. http://www.biology.arizona.edu/CELL_BIO/tutorials/meiosis/page3.html#:~:text=%20Metaphase%20I%3A%20Bivalents%2C%20each%20composed%20of%20two,homologue%20for%20each%20chromosome.%20Anaphase%20I%3A%20Chiasmata%20separate.
