Mitosis

During interphase

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

• 2 new nuclei form

• 2 new identical cells are created

• 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

During telophase

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

• centrioles and spindle fibers appear

• Each DNA gets pull to the opposite sides of the cell

• 2 new nuclei form

During cytokinesis

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

• Cell membrane pinches to make 2 new identical daughter cells

• Each DNA gets pull to the opposite sides of the cell

• 2 new nuclei form

Why do cells go through mitosis?

• to make food from sunlight

• to create proteins

• to get air into the cells

• to replace cells, grow and repair

Daughter cells created by mitosis have

• half of the parents genetic material

• twice the parent cell's genetic material

• an exact copy of the parent cell

• have a brand new DNA structure
