Amayeza aSekwe kwi-DNA aSekwe kuMntu anokuChaphazela uKhathalelo lwezeMpilo ngonaphakade

Umxholo

• Uphengululo lwe

Ngaba ukhe uzive ngathi imiyalelo kagqirha wakho ayihambelani neyona nto ifunwa ngumzimba wakho? Kaloku, awuwedwa. Kwaye kukho iliza elitsha lobugqirha elikufutshane nekona, kuthathwa ngokuba "liyeza elilelakho," elisebenzisa ukulandelelana kwe-DNA ukuphuhlisa unyango olwenzelwe ukujikeleza iijini zakho ezizodwa. (Okwangoku, nazi iindlela ezi-8 zokwenza uninzi lokuQeshwa kwaGqirha.)

Oko kuthetha ntoni: Kwiimeko ezininzi, konke okudingayo sisampulu yegazi okanye umlomo swab kwilebhu yokwenza imephu kwi-DNA yakho, utshilo u-Erica Woodahl, Ph.D., isazi sebhayoloji kwiYunivesithi yaseMontana. "Abantu abanesifo esifanayo abaphathwa ngamayeza afanayo baneempendulo ezahlukeneyo," kuchaza uWoodahl. "Ukuba singalungelelanisa ichiza nemeko ethile yomntu, singaziphucula ezinye zezo mpendulo kwaye sinciphise amathuba okuba abantu baphendule gwenxa." Emva kwayo yonke loo nto, nje ngokuba ubukhulu besithandathu abunakulingana ukuba ubungakanani besibini, ayizizo zonke iindlela zonyango ezilingana nesigulana ngasinye.

Apho Sikhoyo Ngoku

Abantu abaninzi-nkqu nabo bangaphilanga-banomdla wokufunda ngakumbi malunga nezinto zabo zemfuza kunye nendlela ezinokuthi zibenze ngayo ubungozi besifo sabo. Uphando lwakutsha nje lufumanise ukuba iipesenti ezingama-98 zabantu ekuvunyelwene nabo bafuna ukwazi ukuba ngaba iDNA yabo yalatha umngcipheko owandileyo wesifo esisongela ubomi. Uninzi lwabasetyhini kubandakanya, uninzi oludumileyo, u-Angelina Jolie-basebenzise uvavanyo lwemfuza ukuvavanya umngcipheko kwizifo ezinje ngomhlaza wamabele okanye we-ovari, kunye nokuthatha amanyathelo okulungisa le mingcipheko. (Omnye umfazi wabelana "Kutheni Ndifumana uVavanyo lwe-Alzheimer.")

Kwaye uninzi lweenkqubo ezinkulu zokhathalelo lwempilo sele zisebenzisa ulwazi lwe-DNA ukwenza umhlaza ngakumbi kunye neenkqubo zonyango lwesifo sentliziyo. "Unyango olusekelwe kwi-genetic makeup yomntu sele lusetyenziswa kwaye lusebenzayo, ngokukodwa kwiindawo zonyango lomhlaza kunye nesifo senhliziyo," kusho uWoodahl.

Kodwa olu hlobo lwamayeza abhalwe umntu okwangoku alusemgangathweni kwilizwe liphela okwangoku, kwaye uWoodahl uthi ukuthathwa kwezinye iinkqubo zesibhedlele kuye kwacotha kunabantu abaninzi kwicandelo lamayeza enziwe ngeziqu zabo. Ngoba? "Kukho iinkxalabo malunga nokuba ngubani oza kuhlawula uvavanyo, kwaye ngubani oza kucebisa ababoneleli ngedatha yovavanyo," ucacisa. (Zikhuseleke kangakanani iiRekhodi zakho zoNyango zeKhompyutha?)

Ngokusisiseko, oogqirha kunye neenkqubo zesibhedlele zifuna ixesha elininzi lokufumana isayensi. Esi sinokuba sisindululo esinexabiso, nangona sitshiphu ngalo lonke ixesha njenetekhnoloji izuza umhlaba kwiimfuno zomsebenzi.

Kuza ngokukhawuleza

Njengoko ezi ndlela zintsha kunye neetekhnoloji zisamkelwa, isibhakabhaka ngumda xa kufikwa kunyango olusebenzayo okanye kwizitofu zokugonya. Umzekelo omnye: Abaphandi beYunivesithi yaseWashington eSt. Ngokukhomba utshintsho kwisigulana ngasinye, abaphandi babenako ukwenza izitofu zokunyusa ukomelela kwezigulana ezibulala umhlaza T-iiseli.

Izifundo ezingaphezulu ezinje ngale incinci zicwangcisiwe. Ukuba baphumelele ngokulinganayo, bonke abantu abanesifo se-melanoma banokufumana olu hlobo lonyango oluthile lwe-DNA. Yinto enye nje eyenzekayo-ngoku-ngoku indlela amayeza abonisa ukuba aphucula ngayo ukhathalelo lwempilo. (PS: Ngaba ubusazi ukuba i-Endurance Sports yenza i-DNA yakho isempilweni?)

Ngelixa elizayo

Iyeza lomntu siqu linokuphucula unyango ngokukhawuleza kuyo yonke into ukusuka kwingxaki yempilo yengqondo ukuya kulawulo lweentlungu, utshilo uWoodahl. Enye into enokubakho kukufumana idosi efanelekileyo kunye namandla amachiza kwabo banexinzelelo-okuthi, okwangoku, kungqineke ngokungafaniyo. Ulwazi olusekwe kwi-Gene kufuneka luncede oogqirha bachaze iidosi ezisebenzayo, ezichanekileyo, utshilo uWoodahl. Ulindele inkqubela phambili efanayo kwiipilisi zentlungu, unyango lwezifo ezosulelayo, kunye neziyobisi zokuphazamiseka kwemithambo-luvo njengokuxhuzula. Inokuba lutshintsho olukhulu kwishishini lezempilo, kwaye, ngethamsanqa, kuvakala ngathi siya kuba ngabaxhamli abakhulu.
