In a prometaphase cell
Prometaphase is the phase of mitosis following prophase and preceding metaphase in eukaryotic somatic cells. In prometaphase, the nuclear membrane breaks apart into numerous "membrane vesicles," and the chromosomes inside form protein structures called kinetochores. Kinetochore microtubules emerging from the centrosomes at the poles (ends) of the spindle reach the chromosom… WebFeb 4, 2024 · Regardless, some really important things occur during prometaphase that propel cell division along and that help explain what happens in metaphase. …

WebJan 7, 2024 · When we released RepID-proficient HCT116 cells from a nocodazole cell cycle block, which stalls cells in prometaphase, BUB3 levels decreased after mitosis, remained low during the G1 phase, and increased during the late S and G2 phases (Fig. 3c). In contrast, those levels remained high and constant in RepID-deficient cells subject to the … in wall workout machineWebDuring early prometaphase, the cell shape changes, the interphase array of MTs is reorganized, and MT dynamics drastically increase as MTs invade an opened nuclear space packed with chromosomes .
