Telomere DNA contains the T-loop structure, where the telomere end folds back on itself and the 3′ G strand overhang invades into the double-stranded DNA, so it is called D-loop (Palm and de Lange … Telomerase restores short bits of DNA known as telomeres, which are otherwise shortened after repeated division of a cell via mitosis. In normal circumstances, where telomerase is absent, if a cell divides recursively, at some point the progeny reach their Hayflick limit, which is believed to be between 50 and 70 cell divisions.
