<prompt> Fingqa isihloko: Isikhundla esiphakeme emphakathini sinamalungelo aso - ngisho nasezilwaneni zasendle. Abacwaningi abacwaninga ngezimpungushe ezinamabala eKenya bathola ukuthi amalungu aphakeme esizwe aphila isikhathi eside, anempilo engcono futhi aze abe nenzalo eningi. Lolu cwaningo lwenziwa ngokuhlaziya ubude bama-telomere - izembozo ezisemaphethelweni entambo ngayinye ye-DNA - okubhekwa njengezimpawu ezibalulekile zokuguga nokucindezeleka ezinhlotsheni eziningi zezinto eziphilayo, kuhlanganise nabantu. Abacwaningi bahlaziya isimo nempilo yezimpungushe ezinamachashazi eKenya isithombe esivela esitokisini. Bathola ukuthi amalungu aphakeme eqenjini aphila isikhathi eside futhi anempilo kakhudlwana futhi la ma-alpha female atholakala futhi enenzalo eningi. Lokhu kwatholakala ngokuhlaziya ubude bama-telomere. UNora Lewin wasemnyangweni wezilwane waseMichigan State University wathi: Uma ufuna ukubona ukuhleleka kwezimpungushe ezinamachashazi, phonsa inyama entsha eduze kwazo. Ngokushesha kuyacaca ukuthi ubani ophetheyo nokuthi ubani ongekho. Kodwa wayefuna ukwazi ukuthi lezi zimpawu ezingokwemvelo esezinesikhathi eside zamukelwa zaziyokusekela yini lokho ayekubona emkhakheni. UNksz Lewin wasebenza nomunye umbhali oholayo kanye nesazi sezilwane sase-MSU uKay Holekamp ukuze bafunde iminyaka engaphezu kwengu-25 yedatha yama-hyena ezweni lonke lase-Afrika. Ama-telomere ayizigqoko ezisekugcineni kwe-DNA ngayinye ezivikela ama-chromosome ekuwohlokeni. La ma-biomarker abhekwa njengezimpawu ezibalulekile zokuguga nokucindezeleka ezinhlotsheni eziningi, kuhlanganise nabantu. Ukwehla kwama-telomere kuyisibonakaliso sokuthi amangqamuzana aseqala ukuzivikela, izenzo ezicindezelayo ezingase ziholele ngokushesha ekufeni kwamangqamuzana - nokomuntu noma kwesilwane. Ama-hyena asezingeni eliphakeme ayenama-telomere amade kunamanye. Kubantu abasebasha, ama-telomere anobude obungama-nucleotide angaba ngu-8 000 kuya ku-10 000. Nokho, ziyancipha ekuhlukaneni ngakunye kwamangqamuzana, futhi lapho zifinyelela ubude obubucayi ingqamuzana liyayeka ukuhlukana noma liyafa. Leli washi langaphakathi lenza kube nzima ukugcina amangqamuzana amaningi ekhula endaweni yokucwaninga isikhathi esingaphezu kokuphindeka kabili kwamangqamuzana ambalwa. Wabuye wachitha ihlobo eKenya ebuka indlela izimpungushe eziphila ngayo. Iqembu labacwaningi lagxila kuma-telomere, amakepisi avikela ama-chromosome...  <response>: Abacwaningi bahlaziya isimo nempilo yezimpungushe ezinamabala eKenya. Bathola ukuthi amalungu aphakeme eqenjini aphila isikhathi eside futhi anempilo. Lezi zinsikazi ze-alpha nazo kwatholakala ukuthi zinenzalo eningi. Ukutholwa kwenziwa ngokuhlaziya ubude bama-telomere. Lezi zigqoko ezisekugcineni kwe-DNA ngayinye zibhekwa njengezimpawu ezibalulekile zokuguga nokucindezeleka ezinhlotsheni eziningi, kuhlanganise nabantu. Izimpisi eziphakeme zazinama-telomere amade kunezontanga zazo.
