Ekuphishekeleni ubusha nobungqabavu baphakade, ososayensi baye bagxilisa ukunaka kwabo esicini esiphawulekayo nesiyisisekelo se-biology yethu—ama-telomere. Lezi "caps" ezivikelayo ekugcineni kwama-chromosome zidlala indima ebalulekile ekuhlukaniseni amaseli kanye nokuguga kukonke. Njengoba sikhula, ama-telomere ayafinyela ngokwemvelo, okuholela ekungasebenzini kahle kwamangqamuzana, ukuvuvukala, nezifo ezihlobene nobudala. Kodwa-ke, ucwaningo lwakamuva luye lwembula izindlela zokuvikela ngisho nokwelula ama-telomere, okuhlinzeka ngamasu angenzeka okunciphisa inqubo yokuguga.
Ama-telomere ayingxenye ebalulekile ye-DNA futhi adlala indima ebalulekile ekugcineni ubuqotho nokuzinza kwezakhi zofuzo. Lezi zikepisi ezivikelayo, ezitholakala ekugcineni kwama-chromosome ethu futhi ezakhiwe ngokulandelana kwe-DNA, zivimbela ukulahleka kolwazi lofuzo phakathi nokuhlukana kwamaseli.
Ama-telomere adlala indima ebalulekile enqubweni yokuguga. Njengoba sikhula, amangqamuzana ethu ayaqhubeka ehlukana, futhi ama-telomere ayafinyela kancane kancane isikhathi ngasinye lapho ingqamuzana lihlukana khona. Lapho ama-telomere eba mfushane kakhulu, enza kusebenze izimpendulo zamaselula ezivimbela ukuhlukana okuqhubekayo futhi ngaleyo ndlela kuvimbele ukuphindaphinda kwe-DNA eyonakele. Lesi yisivikelo esibalulekile ekuthuthukisweni kwamangqamuzana omdlavuza, njengoba kunciphisa amathuba okukhula okungalawuleki nokuhlukana.
Ngaphezu kwalokho, ukufinyezwa kwama-telomere nakho kungaba nomthelela enqubweni yokuguga ngokwayo. Lapho ama-telomere efinyelela ubude obufushane kakhulu, amangqamuzana angena esimweni sokufa kwengqamuzana futhi ayeke ikhono lokuphindaphinda. Ukunciphisa okuqhubekayo kwama-telomere kuhlotshaniswa nokuguga kwamaselula kanye nokuthuthukiswa kwezifo ezihlobene neminyaka, kuhlanganise nesifo senhliziyo, isifo sikashukela, kanye nezifo ze-neurodeergenerative.
Nakuba ukufinyezwa kwe-telomere kuyinqubo engokwemvelo eyenzeka njengoba sikhula, izici ezithile zokuphila kanye nezingcindezi zemvelo zingasheshisa le nqubo. Izinto ezinjengokucindezeleka okungapheli, ukudla okungenamsoco, ukuntuleka kokuvivinya umzimba, ukubhema, nokuchayeka ebuthini kuhlotshaniswa nokuncipha okusheshayo kwe-telomere, okuholela ekugugeni ngaphambi kwesikhathi nokwanda kokungenwa yizifo ezihlobene nobudala.
I-telomeres iwukulandelana kwe-DNA okuphindaphindayo okwenza ungqimba oluvikelayo ekugcineni kwama-chromosome. Zivikela ekugugulekeni kwezakhi zofuzo ezibalulekile ngesikhathi sokuhlukaniswa kwamaseli. Nokho, ngokuphindaphinda kweseli ngakunye, ama-telomere aba mfishane ngokwemvelo. Le nqubo yokunciphisa ixhumene nokuguga, njengoba amangqamuzana efinyelela iphuzu lapho ama-telomere eba mfushane kakhulu, abangele ukubukeka kwamangqamuzana futhi ekugcineni afe. Ukufinyezwa okuqhubekayo kwama-telomere ekuhlukaniseni amaseli kuhlotshaniswa nenqubo yokuguga yomzimba iyonke.
Lapho ama-telomere eba mafushane kakhulu, amangqamuzana angena esiteji esibizwa ngokuthi i-cell senescence. Phakathi nalesi sigaba, amangqamuzana alahlekelwa amandla okuhlukanisa futhi anda, angasebenzi kahle, futhi aholele ekuwohlokeni kwezicubu nezitho ezihlukahlukene. Lokhu konakala kubonakala ezifweni ezihlobene neminyaka njengesifo senhliziyo, izifo ze-neurodegenerative, nomdlavuza.
