Iqela lezazinzulu elikhokelwa ngabaphandi abavela kwiYunivesithi yaseCaltech lakwazi ukuthatha inyathelo elincinci kodwa elibalulekileyo ekuphuhliseni iikhomputha zekhemikhali ezilungiselelwe ngokukhululekileyo. Njengezinto ezisisiseko zokubala kwiinkqubo ezinjalo, kusetyenziswa iiseti ze-DNA, ezithi ngokobume bazo bendalo zikwazi ukuzilungelelanisa nokuzikhulisa. Yonke into efunekayo kwiinkqubo ze-computing ezisekelwe kwi-DNA zisebenza ngokufudumeleyo, amanzi amdaka, i-algorithm yokukhula efakwe kwi-DNA, kunye nesiseko esisisiseko sokulandelelana kwe-DNA.
Ukuza kuthi ga ngoku, "ikhompyuter" kunye ne-DNA yenziwe ngokungqongqo kusetyenziswa ulandelelwano olunye. Iindlela zangoku bezingafanelekanga ukubala okungenasizathu. Izazinzulu zaseCaltech zikwazile ukoyisa lo mda zaza thaca itekhnoloji enokuthi isebenzise i-algorithms engafanelekanga kusetyenziswa iseti enye yesiseko sezinto ze-DNA ezinemiqathango kunye nesampulu yama-355 okulandelelana okusisiseko kwe-DNA enoxanduva lwe-algorithm "yokubala" - i-analogue yemiyalelo yekhompyuter. "Imbewu" enengqiqo kunye nesethi "yemiyalelo" ifakwe kwisisombululo se-saline, emva koko ukubala kuqala-indibano yokulandelelana.
Into esisiseko okanye "imbewu" yi-DNA fold (DNA origami) - i-nanotube 150 nm ubude kunye ne-20 nm ububanzi. Isakhiwo "sembewu" sihlala singatshintshi kungakhathaliseki ukuba i-algorithm iya kubalwa. Umda βwembewuβ uyilwe ngendlela yokuba ekupheleni kwawo kuqalise ukulandelelana kweDNA. Umcu okhulayo we-DNA waziwa ngokudityaniswa ukusuka kulandelelwano oluhambelana nolandelelwano olucetywayo kwisakhiwo semolekyuli kunye nokwakheka kweekhemikhali, kwaye hayi ngokungacwangciswanga. Ekubeni i-periphery "yembewu" imelwe ngendlela yamasango amathandathu anemiqathango, apho isango ngalinye linamagalelo amabini kunye neziphumo ezimbini, ukukhula kwe-DNA kuqalisa ukuthobela ingqiqo enikiweyo (i-algorithm) ethi, njengoko kukhankanyiwe ngasentla, imelwe isethi enikiweyo yolandelelwano lwe-DNA ye-355 esisiseko ebekwe kwiinketho zesisombululo.
Ngexesha lovavanyo, izazinzulu zibonise ukuba kunokwenzeka ukwenza i-algorithms engama-21, kubandakanywa ukubala ukusuka kwi-0 ukuya kwi-63, ukukhetha inkokeli, ukugqiba ulwahlulo ngabathathu kunye nabanye, nangona yonke into ingaphelelanga kule migaqo. Inkqubo yokubala iqhubeka inyathelo ngenyathelo, njengoko imisonto yeDNA ikhula kuzo zonke iziphumo ezintandathu ze βmbewuβ. Le nkqubo inokuthatha usuku ukuya kwiintsuku ezimbini. Ukwenza "imbewu" kuthatha ixesha elincinci kakhulu - ukusuka kwiyure ukuya ezimbini. Isiphumo sezibalo sinokubonwa ngamehlo akho phantsi kwe-electron microscope. Umbhobho utyhila kwiteyiphu, kwaye kwiteyiphu, kwiindawo zexabiso elithi "1" ngalinye kulandelelwano lweDNA, imolekyuli yeprotheni ebonakala phantsi kwemicroscope iqhotyoshelwe. Oo-zero ababonakali nge-microscope.
Ngokuqinisekileyo, kwifom eveziweyo, iteknoloji ikude ukwenza izibalo ezipheleleyo. Ukuza kuthi ga ngoku kufana nokufunda iteyiphu kwi-teletype, yolulwe ngaphezulu kweentsuku ezimbini. Nangona kunjalo, itekhnoloji iyasebenza kwaye ishiya indawo eninzi yokuphucula. Kuye kwacaca ukuba singahamba kweliphi icala, kwaye yintoni ekufuneka yenziwe ukusondeza iikhompyutha zemichiza.
