Web11 jul. 2024 · The mitosis phase order is— prophase, prometaphase, metaphase, anaphase, and telophase. Each phase consists of characteristic steps in the process of alignment and separation of chromosomes. Once mitosis is over, the entire cell divides in two by a process called cytokinesis. Prophase Web3 nov. 2024 · Since mitotic metaphase was significantly shorter in H1 cells than in somatic cells, we explored the spindle assembly checkpoint during H1 cell division. The localization of the spindle assembly checkpoint marker BUB1 was examined by immunofluorescence in H1 and HeLa cells during mitosis.
