WebPrometaphase Prometaphase begins when the nuclear envelope disassembles, exposing nuclear structures and its contents to the cytoplasm. The nuclear envelope is composed … WebDuring 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 . This initiates interactions between MTs and kinetochores, resulting in the formation of the mitotic spindle and the alignment of chromosomes to the ...

WebMitosis is nuclear division plus cytokinesis, and produces two identical daughter cells during prophase, prometaphase, metaphase, anaphase, and telophase. Interphase is often included in discussions of mitosis, but interphase is technically not part of mitosis, but rather encompasses stages G1, S, and G2 of the cell cycle. Interphase & mitosis WebTo begin, let’s explore the different stages of mitosis. Prophase is the first stage of mitosis. In prophase, chromosomes condense and become visible. spindle fibers emerge from the centrosomes. nuclear envelope breaks …
