WebMar 13, 2024 · During telophase, the cell forms two new nuclear membranes around the two identical groupings of chromosomes. The cell elongates and the cellular membrane prepares to split. Cytokinesis is the final step of mitosis, in which the membrane of the elongated cell begins to pinch together along the cell's equator until the membranes meet. WebThe nucleoli disappear, the nuclear membrane disintegrates. The meiotic spindle, which is responsible for dividing a single parental cell into two daughter cells, forms. Metaphase I.
