WebM phase. A nuclear division (mitosis) followed by a cell division (cytokinesis). The period between mitotic divisions - that is, G1, S and G2 - is known as interphase. Mitosis. Mitosis is a form of eukaryotic cell division that produces two daughter cells with the same genetic component as the parent cell. WebMultiple fission is a cell cycle variation leading to the production of more than two daughter cells.
