Ithimba lososayensi eliholwa abacwaningi baseCaltech University likwazile ukuthatha isinyathelo esincane kodwa esibalulekile ekuthuthukisweni kwamakhompyutha amakhemikhali ahlelekayo ngokukhululekile. Njengezinto eziyisisekelo zokubala ezinhlelweni ezinjalo, kusetshenziswa amasethi e-DNA, okuthi ngomongo wawo wemvelo abe namandla okuzihlela nokukhula. Okudingekayo ukuze amasistimu ekhompyutha asekelwe ku-DNA asebenze amanzi afudumele, anosawoti, i-algorithm yokukhula efakwe ikhodi ku-DNA, kanye nesethi eyisisekelo yokulandelana kwe-DNA.
Kuze kube manje, "ikhompyutha" nge-DNA yenziwe ngokuqinile kusetshenziswa ukulandelana okukodwa. Izindlela zamanje bezingafanele ukubala okungahleliwe. Ososayensi abavela eCaltech bakwazile ukunqoba lo mkhawulo futhi bethula ubuchwepheshe obungakwazi ukusebenzisa ama-algorithms angenasizathu kusetshenziswa isethi eyodwa eyisisekelo yezakhi ze-DNA ezinombandela ezinemibandela kanye nesampula yama-355 ayisisekelo alandelanayo anesibopho se-algorithm “yesibalo” - i-analogue yemiyalelo yekhompyutha. "Inzalo" enengqondo kanye nesethi "yemiyalo" yethulwa esisombululo saline, emva kwalokho ukubala kuqala-ukuhlanganiswa kokulandelana.
Isici esiyisisekelo noma "imbewu" i-DNA fold (i-DNA origami) - i-nanotube engu-150 nm ubude no-20 nm ububanzi. Isakhiwo “sembewu” sihlala singashintshile kungakhathaliseki ukuthi iyiphi i-algorithm ezobalwa. Uhlangothi ‘lwenzalo’ lwakhiwa ngendlela yokuthi ekugcineni kuqale ukuhlanganiswa kokulandelana kwe-DNA. Umucu okhulayo we-DNA waziwa ngokuthi uhlanganiswa kusukela ekulandelaneni okuhambisana nokulandelana okuhlongozwayo kwesakhiwo samangqamuzana nokwakheka kwamakhemikhali, hhayi ngokungahleliwe. Njengoba indawo ezungezile “yembewu” imelelwe ngendlela yamasango anemibandela ayisithupha, lapho isango ngalinye linemifantu emibili kanye nemiphumela emibili, ukukhula kwe-DNA kuqala ukulalela ingqondo enikeziwe (i-algorithm) ethi, njengoba kushiwo ngenhla, imelelwe isethi enikeziwe yokulandelana kwe-DNA yama-355 ayisisekelo abekwe kuzinketho zesixazululo.
Ngesikhathi sokuhlolwa, ososayensi babonisa ukuthi kungenzeka ukwenza ama-algorithms angu-21, okuhlanganisa ukubala kusuka ku-0 kuye ku-63, ukukhetha umholi, ukunquma ukuhlukaniswa ngabathathu nabanye, nakuba konke kungagcini kulezi zindlela zokuziphatha. Inqubo yokubala iqhubeka isinyathelo ngesinyathelo, njengoba imicu ye-DNA ikhula kuyo yonke imiphumela eyisithupha “yembewu”. Le nqubo ingathatha kusukela osukwini olulodwa kuya kwezimbili. Ukwenza “imbewu” kuthatha isikhathi esincane kakhulu - kusukela ehoreni kuya kwelesibili. Umphumela wezibalo ungabonakala ngamehlo akho ngaphansi kwesibonakhulu se-electron. Ishubhu livuleka libe yiteyiphu, futhi kutheyiphu, ezindaweni zenani elithi “1” ngalinye ngokulandelana kwe-DNA, kunamathiselwe i-molecule yephrotheni ebonakala ngesibonakhulu. Oziro ababonakali ngesibonakhulu.
Yiqiniso, ngendlela eyethulwe ngayo, ubuchwepheshe bukude nokwenza izibalo ezigcwele. Kuze kube manje kufana nokufunda iteyipu kuhlobo lwe-teletype, olunwetshiwe izinsuku ezimbili. Kodwa-ke, ubuchwepheshe buyasebenza futhi bushiya isikhala esiningi sokuthuthukiswa. Kwacaca ukuthi singahamba ngakuphi, nokuthi yini okufanele yenziwe ukusondeza amakhompyutha amakhemikhali.
