Mitotic spindles attach to kinetochores
WebIn prometaphase, kinetochores appear at the centromeres and mitotic spindle microtubules attach to kinetochores. In metaphase, chromosomes are lined up and each sister … WebKinetochores are important elements of a mitotic checkpoint. Failure of kinetochores to bind to spindle microtubules, or incorrect association such as when both sister kinetochores attach to microtubules from the same spindle pole, results in …
