Telomerase
A reverse transcriptase containing an RNA molecule that functions as the template for the tandem repeat at telomere. It synthesizes telomere to maintain its length after each cell division. It is active in embryonic cells and gametes, inactive in differentiated somatic cells, and reactivated in malignant cells. Telomerase can add one base at a time to the telomeric end of a chromosome. This maintenance work is required for cells to escape from replicative senescence.
telomerase
an enzyme that directs replication of telomeres at the end of DNA strands; a reverse transcriptase that carries its own RNA template; inactive in regular cells, but active in cancerous cells.
