WebThe nuclear membrane and nucleolus start to appear surrounding the chromosome. During the late telophase, it completely reappears. Telophase results in the emergence of two nuclei in a single cytoplasmic cell. Cytokinesis It is the process of partitioning the cytoplasmic components into two new genetically identical cells.

WebDuring mitosis in higher eukaryotic cells, nuclear envelope breakdown (NEBD) occurs and leads to the disassembly of the nuclear membrane and nuclear pore complexes (NPC). This brings about a mixing of nuclear and cytoplasmic macromolecules (open mitosis). On the other hand, in many fungi, mitosis occurs without NEBD (closed mitosis). WebMPT occurs when permeability transition (PT) pores in the mitochondrial inner membrane are opened, leading to mitochondrial depolarization, uncoupling and organelle swelling. When the PT pores are opened in all mitochondria, ATP is depleted and necrotic cell death ensues from the lack of energy.
