Mitosis has to come before because cytokinesis because the chromosomes need to be separated. mitosis to make new cells to replace the damaged cells. chromosomes
Down-regulation of Survivin by Antisense Oligonucleotides Increases Apoptosis, Inhibits Cytokinesis and Anchorage-Independent Growth†. Survivin, a member of the inhibitor of apoptosis protein (IAP) family, is detected in most common human cancers but not in adjacent normal cells. Previous ... Chen...
To show the cell boundary regulation of spindle scaling directly in zebrafish embryos, we pharmacologically inhibited cytokinesis at cell stage 4–8 using cytochalasin B. This perturbation inhibited the formation of new cell boundaries after anaphase while still allowing spindle formation over multiple cel...
the Aurora kinases are critical for maintaining chromosome stability, duplication, maturation and separation of centrosomes, spindle assembly, and cytokinesis [1]. Aurora kinase was first identified in yeast, where
In fission yeast, S phase is initiated soon after mitosis and completed before cytokinesis is finished. Fluorescence-activated-cell-sorting (FACS) analysis of the DNA content of wild-type S. pombe cells therefore shows largely a 2N profile, with a small population of replicating cells displaying ...
aMedian durations of each mitotic phase plotted consecutively from 6 complete egg-share embryos movies and 18 deselected embryo movies during the first mitosis.bQuantification of timing from PNBD or pronuclear fading to furrow ingression (start of cytokinesis) for complete movies of research embryos ...

In agreement with these findings, Aurora B mislocation had previously been reported to result in loss of chromosome alignment and disruption of cytokinesis in the absence of cell death28. Mitotic catastrophe has previously been observed in cells treated with small interfering RNA survivin43. Therefore...
In diplomonads, of course, there are two nuclei, and each must undergo mitosis before actual cytokinesis (cell division). Like many unicellular eukaryotes, some diplomonad species form cysts that are resistant to chemical attack and/or desiccation (Figure 4(b)). In some parasitic forms (e.g...
Thus, examination of the precise spatiotemporal dynamics of Thr470 phosphorylation would be crucial to fully understand the molecular function and regulation of PRC1 in mitosis. It has been shown that multiple microtubule-associ- ated proteins act in concert to orchestrate cytokinesis. In anaphase ...
