WebAs mitosis begins, the interphase bundles of actin and the microvilli disappear, but the mitotic cells maintain a flattened shape. At metaphase the cell is still so flat that both the chromosomes and spindle apparatus are visible through the intact cell membrane. Microvilli reappear in late anaphase above the chromosomes and poles. WebMicrotubules that will form the mitotic spindle extend between the centrosomes, pushing them farther apart as the microtubule fibers lengthen. The sister chromatids begin to coil …
