Technical Details

QF-DE of the separation spindle of a micronucleus apparently near a daughter micronucleus (not in section plane). The spindle is filled with microtubules linked together by bridges or by motor proteins. An intact nuclear envelope with pores encloses the spindle. TEM taken on 5/12/91 by R. Allen with Zeiss 10A operating at 80kV. Neg. 19,800X. Bar = 0.25µm.
