Chromosome segregation: pulling from the poles.
Dual wavelength video microscopy has been used to evaluate how chromatids move poleward upon chromosome separation at anaphase. The data reveal that poleward microtubule flux provides the dominant force for separating chromatids in Drosophila embryos during anaphase A.
