Altered cell

Body cells replicate periodically (through mitosis, or cell division), but normal cells respond to their surrounding cells and replicate only to replace other cells. Sometimes a genetic mutation will cause a cell and its descendants to reproduce even though replacement cells are not needed.

The DNA of the cell highlighted above has a mutation that causes the cell to replicate even though this tissue doesn't need replacement cells at this time or at this place.
