^*Late prometaphase chromosomes came from cells with 1–4 monooriented chromosomes.  

^‡ Mature metaphase chromosomes came from cells filmed for 20–21 min after the last monooriented chromosome initiated congression.  

^§ Early anaphase chromosomes came from cells fixed 1–3 min after chromatid separation.  

^‖ Metaphase cells (all chromosomes at the spindle equator) were treated for 10 min with 1.0 μM taxol before fixation.
