During interphase

• DNA lines up in the middle of the cell and DNA attaches to spindle fibers

• 2 new nuclei form

• DNA gets copied

During metaphase

• DNA lines up in the middle of the cell and DNA attaches to spindle fibers

• centrioles and spindle fibers appear

• 2 new identical cells are created

• DNA gets copied
