1.The first stage of mitosis, during which the chromosomes condense and become visible, the nuclear membrane breaks down, and the spindle apparatus forms at opposite poles of the cell. 2.The first stage of meiosis, constituted by a series of events that include the thickening and coiling of ...
Meiosis II proceeds very similarly to mitosis. Prophase II, metaphase II, anaphase II, and telophase II see the same pattern of chromosome alignment, separation of sister chromatids, and cytokinesis. The difference is that in meiosis II, the parent cell is haploid....
Prophase is the first step of cell division in both mitosis and meiosis. Cells undergo mitosis in order for the organism to be able to grow, develop and repair. Think about what happens when you cut your skin; it takes time for the wound to heal. Part of the healing process is your ...
