What are the four phases of mitosis and what is the end result?

It starts with 
Prophase - This is the the longest stage in mitosis, the chromosomes become visible and the centrioles separate and move to opposite poles of the cells.

Metaphase - Second stage, the chromosomes line up across the center of the cell and become connected to the spindle fiber at their centromere

Anaphase - Third stage, the sister chromatids separate into individual chromosomes and are pulled apart.

Telophase - The fourth and last stage, the chromosomes gather at opposite ends of the cell and lose their distinct rod - like shapes. Two new nuclear membranes then form around each of the two regions of DNA and the spindle fibers disappear.

Cytokinesis - This process follows the last stage. Now there are two complete copies of the DNA in two different regions of one cell, the cell membrane will pinch and divide the cytoplasm in half. The result of this would be, two individual cells that are identical to the original cell. Each of these cells will have a complete copy of the DNA and contain all of the organelles that the original cell had. 

The end result is that at the end of the cell division, the two daughter cells will have almost exact copies of their parent cell's DNA.
