WebThe attachment of sister kinetochores by microtubules emanating from opposite spindle poles establishes chromosome bipolar attachment, which generates tension on … WebIt was proposed that delayed centrosome separation promotes syntelic attachment in the vicinity of one pole, which can develop into merotelic attachment by an additional MT approach from the other pole (Figure 5B, part 1). Similar results have been reported after bipolarization of a monopolar spindle .
