List and explain all of the mitosis phases?
Prophase: Chromatin condenses into visible chromosomes. The nuclear membrane breaks down. Spindle fibers begin to form from the centrioles.
Metaphase: Chromosomes line up in the middle of the equator. Spindle fibers attach to the centromeres of each chromosome.
Anaphase: Sister chromatids are pulled apart by the spindle fibers. They move to opposite poles of the cell.
Telophase: Chromosomes uncoil back into chromatin. Two new nuclear membranes form around the sets of chromosomes. The cell has two nuclei now.
