There's an enzyme called telomerase which catalyses the lengthening of telomeres. The enzyme includes a molecule of RNA that serves as a template for new telomere segments. It is usually only present in germ line cells of multicellular organisms. Unfortunately, cancer cells also contain telomerase.
