WebOct 23, 2024 · Mammalian telomeres are TTAGGG repeats that mark chromosome ends. At each cell division, telomeres shorten due to the uncomplete replication of DNA ends. When telomere length shortens to a critical point, cells stop proliferating and enter a state known as replicative senescence (Campisi and d’Adda di Fagagna, 2007). WebMar 26, 2024 · Telomeric DNA are TTAGGG tandem repeats, which are susceptible for oxidative DNA damage and hotspot regions for formation of DNA secondary structures …
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. At the limit the cells become s…
