Match each item to the correct phase

  • Chromosomes become visible and nucleus begins to dissolve.

  • Chromosomes are split and moved to opposite sides of the cell.

  • The cell begins to split, and two new nuclei begin to form.

  • Chromosomes attach to spindle fibers and align along the center of the cell.

  • Prophase

  • Metaphase

  • Anaphase

  • Telophase
