Mitosis

Mitosis is when a cell reproduces itself by splitting to from two identical offsprings.

The cell has two copies of its DNA all spread out in long strings

Before the cell divides, the DNA forms X-Shaped chromosomes. Each "arm" of a chromosome is an exact of the other

The chromosomes then line up at the center of the cell and cell fibers pull them apart. The two arms of each chromosomes go to opposites ends of the cell.

Membranes from around each of the sets of chromosomes. These become the nuclei of the two cells

Lastly , the cytoplasm divides

Two new cells containing exactly the same DNA- they are identical to each other and to the parent cell.
