What makes immortal cells so unique is their lack of a hayflick limit which means they can divide as many times as they wish and still remain alive. The only way to get rid of an immortal cell is to kill it. Some examples of immortal cells or cells that reflect no hayflick limit are bacteria cells, cancer cells, sperm cells and ova cells. Inside every cell there is a nucleus and contained in that nucleus is chromosomes. At the tip of each chromosome there is a telomere. The function of these telomeres is to keep the ends of chromosomes from sticking together, and from sticking to other present chromosomes. Telomeres play a very vital role in cellular aging and every time a cell divides its telomeres
