Telomerase - (pronounced) (teh-LOH-meh rays) An enzyme in cells that helps keep them alive by adding DNA to the telomeres (the ends of the chromosomes). With each cell division, telomeres lose a small amount of DNA and become shorter. Over time, the chromosomes become damaged and the cells die. Telomerase helps prevent this. Cancer cells usually have more telomerase than most normal cells
