WebMar 6, 2024 · The cleavage furrow is an area of cell surface invagination that occurs during the process of cytokinesis. The cleavage furrow forms as a result of the assembly and subsequent constriction of an actin-myosin II ring, carefully positioned in the equatorial cell cortex and connected to the plasma membrane. WebMitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase). These phases occur in strict sequential order, and cytokinesis - the process of dividing the cell contents to make two new cells - starts ...
