| |
| | Definition: | | An enzyme composed of RNA and protein components which prevents the shortening of telomeres - the stabilizing caps on the ends of chromosomes. Telomeres shorten whenever a cell divides; when the telomeres become very small, the cell stops dividing. Telomerase is present in cells which are rapidly dividing, such as in embryos and tumors. |
