Proteins required for cytokinesis are activated by _____ during mitosis
Remnants of mitotic spindle are required for assembly of
replicated chromosomes condense, mitotic spindle assembles between 2 centrosomes
in prometaphase, chromosomes can now attach to spindle microtubules via

pushing and pulling forces contribute to
when _____ stabilize, microtubule instability increases
When ______ destabilize, microtubule instability increases
rapid ______ results in survival of only productive microtubules
