Two side-by-side fluorescence time-lapse movies of egg extract spindle assembly reactions containing rhodamine labeled tubulin are shown over the time interval of 38 min. On the left is a spindle formed around an RCC1-coated bead (green), and on the right a spindle assembled around a chromatin-coated bead (blue). Note that the RCC1 bead spindle is smaller, and that the bead oscillates from pole-to-pole.
