WebMitosis is different from meiosis is several key ways. The chromosomes line up on the metaphase plate during meiosis and mitosis, but unlike in mitosis, meiosis has paired chromosomes or tetrads which line up on the metaphase plate. By contrast, mitosis has single chromosomes line up on this plate instead. WebMitotic kinetochores are initially captured by dynamic microtubules via a ‘search-and-capture’ mechanism. The microtubule motor, dynein, is critical for kinetochore capture as it has been shown to transport microtubule-attached chromosomes towards the spindle pole during early mitosis. The microtubule-binding Ndc80 complex that is recruited to …
