WebWhat are the different phases of a cell cycle: The different phases of a cell cycle include: Interphase – This phase includes the G1 phase, S phase and the G2 phase. M phase – This is the mitotic phase and is divided into prophase, metaphase, anaphase and telophase. Cytokinesis – In this phase the cytoplasm of the cell divides. Web24 feb. 2024 · PANS1 is a key inhibitor of SEPARASE, the enzyme responsible for triggering anaphase by cleaving Cohesin, which is the complex holding the sister chromatids together. Separase must be tightly regulated to prevent the precocious release of chromatid cohesion and a catastrophic chromosome separation.
