Conditions of Use
Cells divide/multiply using a large array of steps. First the chromosome splits into two identical chromosomes. Next the genetic material in the nucleus of the cell begins to thicken and shorten. The chromosome copies are held together at their centers so they form a sort of 'x'. Then the 'x's line up at the center of the cell. Then the copies separate, and each copy of the chromosomes are moved to either side of the cell towards each nuclei. To finish up the cell division the cytoplasm pinches at the center of the cell-dividing it in 2.
Interphase: The busiest stage where the cell is preparing for the division.
Prophase: The chromosome makes an exact copy of itself. The chromosome copies are held together at their centers so they form a kind of 'x'.
Metaphase: the nuclei move to either side of the cell and the chromosome 'x's move to the center while the DNA fibers are shortening and thickening and separated evenly to each side of the cell.
Anaphase: The 'x' split up and both the chromosomes and the DNA fibers split to either side of the cell.
Telophase: The cytoplasm pinches at the center of the cell-dividing it in two.
