Chromosome in anaphase
WebNov 20, 2024 · You might remember from above that it is the protein cohesin that holds together sister chromatids in metaphase of mitosis and metaphase II of meiosis. However, in meiosis I homologous chromosomes must be held together in metaphase I, before these ties are swiftly broken during anaphase I. WebMay 27, 2024 · Generally, anaphase I involve separating the chromosomes from each sister chromatid to the opposite poles still attached to the microtubules of the cell while anaphase 2 involves the actual split of the sister chromatids into single chromatids.
