Ngezinye izikhathi abantu badinga ukunquma ukuthi bahlobene yini nomunye ubuhlobo begazi. Ngokuvamile, lokhu kuhlolwa kwenziwa ukuze kuqinisekiswe ukuthi ungubani.
Ubuchwepheshe banamuhla bukuvumela ukuba uhlolisise ubuntfu ngegazi, amathe, izinwele nezinye, okuthiwa, izinto eziphilayo. Lokhu kuhlaziywa okujwayelekile, okuyinto, noma kunjalo, kungathinta kakhulu impilo yethu. Ukuhlolwa kwe-DNA yezingane kuyenziwa ukuze kuqinisekiswe amalungelo omzali, amalungelo alungelo, futhi ngezinye izikhathi ngisho nokuhlola ukuhlasela kwezifo ezibucayi.
Indlela yokwenza ukuhlaziywa kwe-DNA kubantwana?
Namuhla kulula kakhulu ukuthola ubufakazi bokuba ubaba. Ukuze wenze lokhu, udinga ukuxhumana nomtholampilo, ohlinzeka ngezinsizakalo ezinjalo, futhi unikeze ukuhlaziywa kwezinto eziphilayo ze-usolwa wengane nengane. Indlela elula ukukhipha i-swab emlonyeni (ngaphakathi ngaphakathi kwesigama), kuyilapho i-DNA impahla itholakala ematheni. Ngaphandle kwalokho, kungenzeka ukudlulisa izinwele (ngokuqinisekile ukukhipha "kusuka empandeni"), amazinyo, izipikili, i-earwax. Ukuhlolwa kwegazi kubuye kulungele ukuhlolwa kwezingane, kodwa kulula ukuba odokotela basebenze ngamathe, ngoba ukuhlolwa kwegazi kungase kube ukungaqondisi emva kokumpontshelwa, ukufakelwa komnyofu we-bone, njll. Umphumela wokuhlolwa kwe-DNA wesibindi uzothola ezinsukwini ezimbalwa. Ngesikhathi esifanayo, ukuhlolwa kungaba nomphumela omubi, lapho indoda ingenayo ingane engu-100% noma ubaba oqotho. Amathuba alo mkhuba ngokuvamile avela ku-70 kuya kuma-99%. Kumele kuqashelwe ukuthi idatha yokuhlola i-DNA inesisindo njengobufakazi enkantolo kuphela lapho amathuba okuba ngumzali angama-97-99.9%.
Ukuhlolwa kwezingane zokukhulelwa
Ngezinye izikhathi kuyadingeka ukwenza ukuhlaziywa kwe-DNA ngaphambi kokuzalwa kwengane. Lobu buchwepheshe buvele buhlolwe kamuva - ekuqaleni kokuhlaziywa kwezakhi zofuzo kungenzeka kuphela emva kokubeletha.
Isivivinyo senziwa ngale ndlela elandelayo: Ubaba osolakala ukuthi unikeza ukuhlolwa kwegazi kusukela emthanjeni, futhi amasampula e-DNA we-fetus asuswa egazini likaMama, lapho inani lalo lwazi elanele ukuhlolwa seluvele liqoqiwe ngamasonto angu-9-10 wokukhulelwa. Kunezinye izindlela zokwakheka kwesibalo se-fetal biological, isibonelo, ukukhishwa kwe-amniotic (isisindo samanzi e-fetal fluid). Le ndlela yokunquma ubaba nge-DNA inembile efanayo, kodwa kuyingozi nakakhulu ngenxa yokwesabisa kwezinkinga ngisho nasekupheleni kokukhulelwa, ngakho odokotela ngokuvamile bancoma ukugwema ekungeneni okunjalo.
