Science / Biology / Mitosis: The division of the cells nucleus and nuclear material of a cell; consists of four stages: prophase, metaphase, anaphase, and telophase. Cell xeroxing. Mitosis occurs only in eukaryotes. The DNA of the cell is replicated during interphase of the cell cycle and then segregated during the four phases of mitosis.
Science / Genetics / Isochromosome: A metacentric chromosome produced during mitosis or meiosis when the centromere splits transversely instead of longitudinally: the arms of such chromosome are equal in length and genetically identical MORE
Science / Biology / Aster: Short fibers produced by cells during mitosis and meiosis. These radiate from the centriole (if it is present). MORE
