WebJul 7, 2024 · Chromosomes move randomly until they attach (at their kinetochores) to polar fibers from both sides of their centromeres. Chromosomes align at the metaphase plate at right angles to the spindle poles. Chromosomes are held at the metaphase plate by the equal forces of the polar fibers pushing on the centromeres of the chromosomes. WebDuring prophase I, homologous chromosomes pair up and exchange sections of DNA. This is called recombination or crossing over. This is followed by metaphase I where the …
