nounkʌɪˈniːtəʊkɔːkɪˈniːtəʊkɔːkəˈnetəˌkôr

 Example sentencesExamples
-  A second checkpoint pathway, the spindle checkpoint, operates at a similar point in meiosis, preventing progression into anaphase if the spindle apparatus fails to connect appropriately with kinetochores.
 -  In metaphase, sister kinetochores attach to microtubules emanating from opposite spindle pole bodies during alignment of the chromosomes.
 -  Chromosome loss may be the result of either non-attachment of the chromosome kinetochore to the spindle microtubules or chromosome lagging at anaphase and gives rise to a micronucleus.
 -  The DNA is asymmetrically distributed to the daughter cells when the kinetochores do not attach and the spindle checkpoint does not restrain mitosis.
 -  This cohesion or ‘chiasma binder’ function ensures the generation of a bipolar spindle in which tension is generated at the kinetochores.
