Mitosis is the process by which cells reproduce from one parent cell into two identical daughter cells.  It is divided into 4 phases: Prophase, metaphase, anaphase, and telophase. 

In Prophase, the chromosomes condense into visible threads that grow thicker and shorter.  The Chromosomes duplicate into sister chromatids, connected by a structure called the centromere.  Centrioles become visible, and move to opposite ends of the cell, remaining connected to each other through a mechanism called spindles. 

In metaphase the centromeres attach to the center of the spindle. 

In anaphase the sister chromatids separate becoming identical chromosomes, and the spindles pull the chromosomes to the opposite ends of the cell. 

In telophase, the cell splits at the equator, and the chromosomes uncoil and become invisible.  Each daughter cell is an exact clone of the original cell.
