Early embryonic divisions in Drosophila are syncytial. Nuclei undergo mitosis synchronously for the first 14 nuclear cycles, followed by cellularization (Foe and Alberts, 1983). At nuclear cycle 10, n...

This movie is of a Drosophila melanogaster early embryo (cycle 12) expressing GFP-tubulin (green) and injected with Rhodamine-labeled histones (red) and 8mg/ml RanT24N, a dominant negative inhibitor o...

Movie shows spindle assembly around DNA-beads in a Xenopus laevis egg extract. DNA beads are autofluorescent, and spindle is formed from exogenous X-rhodamine-labeled tubulin. By the end of the movie...

Movie shows spindle assembly around DNA-beads in a Xenopus laevis egg extract. DNA beads are autofluorescent, and spindle is formed from exogenous X-rhodamine-labeled tubulin and alexa-488 labeled an...

Effect of depletion of Nup133 and Nup43 by antibody addition on spindle assembly on sperm chromatin in Xenopus oocyte extract. Spindles (red) were localized by addition of tubulin-rhodamine and chrom...

This HeLa cell, which is expressing both a kinetochore marker (EGFP-CENP-B) and a centrosome marker (Venus-centrin), has been depleted of the spindle assembly checkpoint protein Mad2. In the absence o...

The time-lapse movie made in 1974 shows meiosis in spermatocytes of Chrysochraon japonicas (grasshopper) as seen with the polarizing microscope. The principal birefringent components are the spindle m...

A time lapse experiment of Saccharomyces cerevisiae expressing GFP tagged MAD2. MAD2 is a non-essential gene that encodes a component of the spindle checkpoint. The spindle checkpoint delays the o...
