<prompt> Fingqa isihloko: Lapho ngicabanga ngosuku lwami lokugcina emhlabeni, futhi ngizama ukungacabangi ngalo njalo, ngicabanga ngosuku olunelanga emaphandleni nokuhambahamba phakathi kwama - narcissus namasimu aluhlaza. Ngidla ukudla okumnandi nezingane zami nabazukulu - mhlawumbe nabazukulu bami emphupheni yami, sengimdala kakhulu kodwa ngisesesimweni esihle ngempela - bese kuthi, ngemva kwengilazi noma ezimbili ze-champagne, ngiwele ebuthongweni obujulile obungenamaphupho engingasoze ngavuka kubo. Ngiyazi ukuthi angifuni ukuhamba njengoba kwenza umama, ngiqaphela ngokugcwele ukuthi ukufa kwakuseduze futhi kufanele ngibhekane nosizi lwabantu ababemthanda. Kodwa okungenani umama, umbhali uJocasta Innes, wayephilile engqondweni kwaze kwaba yilapho umdlavuza wepancreatic uqeda ukuphila kwakhe eminyakeni emibili edlule, eneminyaka engu-78 ubudala. Umbhali uDaisy Goodwin wasebenzisa isevisi yaseMelika yokuhlela i-DNA ukuze athole ukuthi wayenezakhi zofuzo eziguqukile yini noma cha ezingase zikhuphule ingozi yakho yomdlavuza webele nowama-ovari, isifo sikaParkinson nesifo sika-Alzheimer. Ugogo wami ompofu u-Eileen wayengenakho lokho: wafela enkungwini yokudideka ngokwengqondo, ebuka izingane zakhe njengokungathi zingabafokazi. Ingabe ikhona indlela enhle yokufa? Iningi lethu alazi ukuthi sizosuka kanjani kulesi simo sokufa - cishe ukuphela kwento esenza sihlale siphilile engqondweni. Kodwa manje ososayensi banikeza abantu abafuna ukubona ikusasa labo insizakalo. Ngama-125, ungathumela isampula likamathe akho enkampanini yaseMelika, bese bona bakuthumele indaba yakho ephelele, kuhlanganise nokhokho bakho futhi - okubaluleke kakhulu - inkomba enhle yokuthi uyomhlangabeza kanjani umenzi wakho. Kwenziwa ngokwenza i-genome yakho ibalazwe, lokho kulandelana okuyingqayizivele kwama-chromosome angu-23 akha i-DNA yakho, kukhomba ngokuqondile ukuguquka kwezakhi zofuzo okunquma ukuthi kungenzeka yini ukuba ufe ngesizotha noma ukuthi kungenzeka yini ukuba ube nesifo esiholela ekufeni okuphilayo. Ukwenza ibalazwe le-DNA kuye kwaziswa umphakathi ngemva kokutholwa kuka-Angelina Jolie ukuthi wayephethe izakhi zofuzo ezaziyokwandisa kakhulu amathuba akhe okuba nomdlavuza wesibeletho nowamabele. Kusukela ngaleso sikhathi uye wahlinzwa amabele kabili, futhi kuleli sonto umemezele ukuthi ube...  <response>: Ugogo kaDaisy Goodwin waba nesifo sokuwohloka komqondo eseminyakeni yawo-70 ubudala. Wahlolwa ukuthi wayenazo yini izakhi zofuzo zesifo sikaParkinson, umdlavuza wamabele nowama-ovari. Ukuhlolwa kwe-DNA kwembula ukuthi usengozini enkulu yokuthola i-Alzheimers.
