Mitosis Cell Cycle

During prophase

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

• DNA condenses into chromosomes, centrioles and spindle fibers appear

• 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 anaphase

• 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

• 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

What is the purpose of mitosis?

• To increase the surface area of a cell
• To allow cells to divide for growth, repair, and renewal
• For increasing genetic variation within a species
• To allow for DNA replication and protein synthesis
