Ososayensi bakhulume ngomphumela wokwephulwa kwezigqi zesifunda eseceleni kwi-DNA yomuntu
Ucwaningo olusha lwesayensi olwenziwe ngesisekelo se-Washington State Laboratory's Laboratory sekwembulile umphumela olimazayo womsebenzi ekushintsheni ebusuku empilweni yabantu. Ukwephulwa kwemigqilasi eseceleni kungaholela ezinguquko ekubonakalisweni kwezincwadi zofuzo ezihlotshaniswa nokwanda okulimazayo. Imiphumela yomsebenzi eyenziwe yashicilelwa ku-New Atlas Magazine.
Kuyaphawuleka ukuthi ngo-2019 i-International Cancer Studgen Agency yamemezela ubungozi bomsebenzi wobusuku. Amagama kaMair aqinisekisiwe ngesikhathi sokuhlolwa achithe ngaphezu kwezinsuku eziyisikhombisa nokuzibandakanya kwamavolontiya anempilo ayi-14. Ingxenye yokuqala yezihloko isebenze amashifu ambalwa ngesikhathi sasemini, kanti owesibili usebusuku. Ngemuva kwalokho, kwadingeka basebenzise amahora angama-24 esimweni sokuphaphama ngaphansi kokukhanyisa njalo. Lokhu kuvumela ososayensi ukuthi bafundele izigqi zabantu, kungakhathalekile ukuthi yiziphi izinto zangaphandle.
Ukuhlaziywa kwakhombisa ukuthi uhlelo lomsebenzi wasebusuku ludutshulwe phansi izigqi zesifunda sezihloko, okuholele ekuphulweni kokubonakaliswa kwezinye izinhlobo zofuzo ezihlobene nokuthuthukiswa kokwakhiwa okulimazayo. Ochwepheshe baphinde baveze umthelela omubi womsebenzi ebusuku kwinqubo yemvelo yokubuyiselwa kwe-DNA.
Ukuze uthole isifundo esinemininingwane esithe xaxa sokwephulwa kokubonakaliswa kwezinhlobo ezithile ngamaseli anempilo emzimbeni, ososayensi bahlaziya amaseli amhlophe egazi, ibathinta besebenzisa imisebe yegazi. Kwavela ukuthi amaseli eqembu labantu asebesebenze ebusuku ashintshiwe athambekele ekulimaleni kwe-DNA okubangelwa kabusha.
Le miphumela iphakamisa ukuthi amashifu asebusuku adida ukuhlinzwa kwegama lomdlavuza ufuzo, ngakho-ke kunciphisa ukusebenza kwezinqubo ze-DNA ye-DNA yomzimba, lapho zidingeka kakhulu, - uJason Mcdermott, ongumbhali we-Studies Comrall.Ososayensi baphawule ukuthi isifundo esisha asibavumelanga ukuba bathole izimpendulo kuyo yonke imibuzo. Njengengxenye yesigaba esilandelayo, kuhlelwa ukuhlaziya i-DNA yabantu abasebenza njalo ubusuku bokushintsha ukuqhathanisa imiphumela yokuhlolwa kokusebenza kwabasebenzi abasebusuku iminyaka eminingana. Futhi azikhiphi amathuba okuba isikhathi eside, umzimba ungazivumelanisa nomsebenzi onjalo.
