Chromosomes stop moving towards the pole
WebNov 17, 2016 · When cohesins are no longer resisting the pull of microtubules in the spindle, sister chromatids separate and move towards opposite poles. Cell membrane invagination then leads to the formation … WebDuring metaphase, all of the chromosomes are aligned in a plane called the metaphase plate, or the equatorial plane, midway between the two poles of the cell. The sister chromatids are still tightly attached to each other. …

WebMitosis ends with telophase, or the stage at which the chromosomes reach the poles. The nuclear membrane then reforms, and the chromosomes begin to decondense into their … WebDec 30, 2024 · Somewhat perversely, even as the chromosomes move towards the spindle poles, the poles themselves move outward slightly. Separation of the sister chromatids requires the dissociation of the molecular “glue” holding them together: the cohesin proteins.
WebThe microtubules attach at each chromosomes’ kinetochores. With each member of the homologous pair attached to opposite poles of the cell, in the next phase, the microtubules can pull the homologous pair apart. A spindle fiber that has attached to a kinetochore is called a kinetochore microtubule. WebMay 7, 2024 · During mitosis, the two sister chromatids that make up each chromosome separate from each other and move to opposite poles of …
