Document Summary
Which one of the following is correct about cytokinesis: Cytokinesis leads to segregation of duplicated chromosomes into daughter nuclei. The first hint of cytokinesis in animal cells apears in metaphase. A cell plate a formed during cytokinesis of an animal cell. The mechanism of cytokinesis in animal cells is in an opposite direction of that of plant cells. An active protease called separase is released . Cdh1 binds apc ubiquinates anaphase inhibitor which is called securin. Separase cleaves cohesins that hold sister chromatids together. anaphase begins when sister chromatids separate. Animal cells and plant cells go through cytokinesis through different mechanisms. Plant cells conduct cytokinesis through an inside to outside mechanism. Plant cells conduct cytokinesis through an outside to inside mechanism. Animal cells conduct cytokinesis through an outside to inside mechanism. Animal and plant cells conduct cytokinesis through an inside to outside mechanism. A phragmoplast uses an inside-out mechanism to form the cell plate.
