Gulu la asayansi motsogozedwa ndi ofufuza ochokera ku yunivesite ya Caltech adatha kuchitapo kanthu kakang'ono koma kofunikira pakupanga makompyuta opangidwa mwaufulu. Monga maelementi owerengera m'makina otere, ma DNA amagwiritsidwa ntchito, omwe mwachilengedwe chawo amatha kudzipanga okha ndikukula. Zomwe zimafunika kuti makina opangira makompyuta a DNA agwire ntchito ndi madzi ofunda, a brackish, algorithm ya kukula yomwe ili mu DNA, komanso magawo oyambira a DNA.
Mpaka pano, "computing" ndi DNA yachitidwa mosamalitsa pogwiritsa ntchito ndondomeko imodzi. Njira zamakono sizinali zoyenera kuwerengera mopanda malire. Asayansi ochokera ku Caltech adatha kuthana ndi izi ndipo adapereka ukadaulo womwe ungathe kugwiritsa ntchito ma aligorivimu mokhazikika pogwiritsa ntchito zida za DNA zomveka bwino komanso zitsanzo za 355 zoyambira za DNA zomwe zimapangitsa "calculation" algorithm - analogue ya malangizo apakompyuta. "Mbewu" yomveka komanso "malangizo" amalowetsedwa mu saline solution, pambuyo pake kuwerengera kumayamba-kusonkhanitsa ndondomekoyi.
Chinthu choyambirira kapena "mbewu" ndi DNA fold (DNA origami) - nanotube 150 nm kutalika ndi 20 nm m'mimba mwake. Mapangidwe a "mbewu" amakhalabe osasinthika mosasamala kanthu za ndondomeko yomwe idzawerengedwe. Mphepete mwa βmbewuβ ya βmbewuβyo imapangidwa mβnjira yakuti pamapeto pake kusanjidwa kwa ndandanda ya DNA kumayambika. Chingwe cha DNA chomwe chikukula chimadziwika kuti chimapangidwa kuchokera kuzinthu zomwe zimagwirizana ndi mamolekyu ndi mankhwala, osati mwachisawawa. Popeza kuti mbali zonse za βmbewuβ zikuimiridwa ngati zipata zisanu ndi chimodzi zokhazikika, pomwe chipata chilichonse chimakhala ndi zolowetsa ziwiri ndi zotuluka ziwiri, kukula kwa DNA kumayamba kumvera malingaliro operekedwa (algorithm) omwe, monga tafotokozera pamwambapa, akuimiridwa ndi DNA yotsatizana ya 355 yoyambira yoyikidwa muzosankha.
Pazoyeserera, asayansi adawonetsa kuthekera kochita ma aligorivimu 21, kuphatikiza kuwerengera kuyambira 0 mpaka 63, kusankha mtsogoleri, kugawikana ndi atatu ndi ena, ngakhale kuti chilichonse sichimangotengera ma algorithms awa. Kuwerengera kumapitirira pang'onopang'ono, pamene zingwe za DNA zimakula pazinthu zonse zisanu ndi chimodzi za "mbewu". Izi zitha kutenga tsiku limodzi mpaka awiri. Kupanga "mbewu" kumatenga nthawi yochepa kwambiri - kuyambira ola limodzi mpaka awiri. Zotsatira za mawerengedwewa zitha kuwonedwa ndi maso anu pansi pa microscope ya electron. Chubucho chimafutukuka kukhala tepi, ndipo pa tepiyo, pa malo a mtengo uliwonse β1β pa ndondomeko ya DNA, puloteni yooneka ndi maikulosikopu imamangidwira. Zero siziwoneka ndi maikulosikopu.
Inde, mu mawonekedwe ake, teknoloji ili kutali ndi kuchita mawerengedwe athunthu. Pakalipano zili ngati kuwerenga tepi kuchokera pa teletype, yotambasulidwa kwa masiku awiri. Komabe, teknoloji imagwira ntchito ndipo imasiya malo ambiri oti asinthe. Zinali zoonekeratu kuti tingasunthire mbali iti, komanso zomwe zikuyenera kuchitika kuti makompyuta a mankhwala aziyandikira.
