WebMetaphase I. During metaphase I, the homologous chromosomes are arranged in the center of the cell with the kinetochores facing opposite poles. The homologous pairs orient themselves randomly at the equator. … Webletion of CDC20 causes cell cycle arrest at metaphase due to the accumulation of Pds1 (15, 23). Deletion of both CDC20 and PDS1 allows the cells to separate their sister chromatids, but the cells cannot exit mitosis due to the presence of Clb5 (15, 23). It is unclear if CDC20 plays an essential role in mitosis in mammals.
WebThe four stages of meiosis II are as follows:-. Prophase II – It immediately sets off after the cytokinesis when the daughter cells are formed. The chromosomes begin to condense accompanied by the dissolution of the nuclear membrane and the disappearance of the Golgi apparatus and ER complex.
