• Kwenziwa kanjani

Ukuhlolwa kwe-DNA kwenziwa ngenhloso yokuhlaziya izinto zofuzo zomuntu, kukhonjwe ushintsho olungaba khona ku-DNA futhi kuqinisekiswe nethuba lokuthuthuka kwezifo ezithile. Ngaphezu kwalokho, ukuhlolwa kwe-DNA okusetshenziswa ekuhlolweni kobaba, okungenziwa nganoma iyiphi into ephathekayo, njengamathe, izinwele noma amathe.

Intengo yokuhlolwa iyahlukahluka kuye ngelabhorethri okwenziwa kuyo, kuhlolwe inhloso kanye nezimpawu zofuzo futhi umphumela ungakhishwa emahoreni angama-24, lapho inhloso kungukuhlola ufuzo oluphelele lomuntu, noma amasonto ambalwa lapho ukuhlolwa kwenziwa ukuhlola izinga lobudlelwano.

Ukuhlolwa kwe-DNA kungakhomba ushintsho olungaba khona kwi-DNA yomuntu, okungakhombisa amathuba okuthuthuka kwezifo kanye nethuba lokuthi zidluliselwe ezizukulwaneni ezizayo, kanye nokuba wusizo ekwazini imvelaphi nokhokho babo. Ngakho-ke, ezinye izifo ezingakhonjwa ukuhlolwa kwe-DNA yilezi:

• Izinhlobo ezahlukene zomdlavuza;
• Izifo zenhliziyo;
• I-Alzheimer's;
• Thayipha 1 bese uthayipha 2 sikashukela;
• Isifo semilenze esingenakuphumula;
• Ukungabekezelelani kwe-Lactose;
• Isifo sikaParkinson;
• ILupus.

Ngaphezu kokusetshenziswa ekuphenyweni kwezifo, ukuhlolwa kwe-DNA kungasetshenziswa futhi ekwelulekeni ngezakhi zofuzo, okuyinqubo yalabo abahlose ukukhomba izinguquko ku-DNA ezingadluliselwa esizukulwaneni esizayo kanye nethuba lalezi zinguquko eziholela isifo. Qonda ukuthi kuyini ukwelulekwa ngezakhi zofuzo nokuthi kwenziwa kanjani.

Ukuhlolwa kwe-DNA kokuhlolwa kobaba

Ukuhlolwa kwe-DNA kungenziwa futhi ukubheka izinga lobudlelwano phakathi kukababa nendodana. Ukwenza lolu vivinyo, kuyadingeka ukuthi kulandwe isampula yebhayoloji kumama, indodana kanye nobaba okusolwa ukuthi ithunyelwa elabhorethri iyohlaziywa.

Yize ukuhlolwa kuvame ukwenziwa ngemuva kokuzalwa, kungenziwa futhi ngesikhathi sokukhulelwa. Bona ukuthi ukuhlolwa kobaba kwenziwa kanjani.

Kwenziwa kanjani

Ukuhlolwa kwe-DNA kungenziwa kunoma isiphi isampula sebhayoloji, njengegazi, izinwele, isidoda noma amathe, isibonelo. Endabeni yokuhlolwa kwe-DNA okwenziwa ngegazi, kuyadingeka ukuthi ukuqoqwa kwenziwe elebhu enokwethenjelwa futhi isampula ithunyelwe ukuyohlolwa.

Kodwa-ke kukhona amanye amakhithi eqoqo lasekhaya angathengwa nge-inthanethi noma kwamanye ama-laboratories. Kulokhu, lo muntu kufanele agcobe i-swab kakotini equkethwe kukhithi ngaphakathi ezihlathini noma akhafulele esitsheni esifanele bese ethumela noma athathe isampula elabhorethri.

E-laboratory, kwenziwa ukuhlaziywa kwamangqamuzana ukuze kuhlaziywe lonke uhlaka lwe-DNA yomuntu, ngaleyo ndlela, kubhekwe izinguquko ezinokwenzeka noma ukuhambisana phakathi kwamasampuli, ngokwesibonelo kobaba, isibonelo.
