telomerase
An enzyme that catalyzes the lengthening of telomeres; the enzyme includes a molecule of RNA that serves as a template for new telomere segments.

Telomerase
Telomerase is an enzyme that adds telomere repeat sequences to the 3' end of DNA strands. By lengthening this strand DNA polymerase is able to complete the synthesis of the "incomplete ends" of the opposite strand.

Telomerase (tee-LAW-mer-ase) An enzyme that adds telomeres to the ends of eukaryotic chromosomes, preventing the chromosome from shrinking during each cell division.
Telomerase The enzyme that directs the replication of telomeres.
Telomere The end of a chromosome. This specialized structure is involved in the replication and stability of linear DNA molecules.

[edit] Telomerase
The HeLa cell line was derived for use in cancer research. These cells proliferate abnormally rapidly, even compared to other cancer cells.
Telomerase
Telomerases are specialized reverse transcriptases that are involved in synthesis of telomeres in most organisms. They prevent the subsequent decline of telomeric ends.
Telomerase is usually found in cells involved in the production of gametes. It is not normally found in somatic cells.
Cyclin-Dependent Kinases
Some cells stop dividing in G1; others stop in G2.
Telomerase and telomeres have been full of surprises for us and there's a great deal we don't understand about exactly how it works. When does telomerase decide to work on a telomere and when does it decide not to?
dividing because the telomeres, protective bits of DNA on the end of a chromosome, become shorter with each division and eventually can no longer protect the chromosome. Cancer cells, on the other hand, are "immortal." An enzyme called telomerase ...
