Question

ntroduction. Mitosis is a process where a single cell divides into two identical cells (cell division). This includes different stages: prophase, metaphase, anaphase and telophase with interphase in between each division. The major purpose of mitosis is for growth and to replace worn out cells A. Go to http://www.cellsalive.com/mitosis.htm and use the control buttons along the bottom to run the complete animation. Learn the different stages of cellular division and answer the following items. Match the following diagrams and descriptions of mitosis to the correct mitotic stage and fill up thetable below. Write the le 1) Description: A. Centromere split separating 2 sister chromatids apart 8. Condensation (thickening) of chromatin C. Nuclear membrane fragmentation and disintegration D. Duplication of DNA occur on this stage. E. Reappearance of nuclear membrane. F. Formation of spindle fibers for chromosome attachment G. Growth of cell occur on this stage. H. Division of the cytoplasm . Alignment of chromosome at the equatorial plate J. Disappearance of spindle fibers
