What are the four phases of mitosis?
Mitosis occurs in prokaryoticeukaryotic cells.
What is the end result of mitosis?
During the final stage of the cell cycle, cytokinesis allows the cell to finish dividing, creating one celltwo cellsthree cells with identicaldifferent copies of DNA.

Explain the process of tissue cultures using healthy cells.
A tissue culture is made by taking healthy cells from a living organism and placing them in a nutrient medium. The cells divide by mitosis and grow into one layer. Once the cells touch, they stop dividing until space becomes available, such as when a cell dies. Healthy cells usually undergo about 20 to 50 mitotic divisions in a tissue culture.
