Mazuvano, tinokwanisa kuwana ruzivo rwese rwevanhu kubva kumakombuta madiki muhomwe dzedu. Yese iyi data inofanirwa kuchengetwa kumwe kunhu, asi maseva akakura anotora nzvimbo yakawanda yemuviri uye anoda simba rakawanda. Vatsvagiri veHarvard vakagadzira hurongwa hutsva hwekuverenga nekunyora ruzivo vachishandisa organic mamorekuru ayo anogona kuramba akagadzikana uye achishanda kwezviuru zvemakore.
Zvinonzwisisika kuti DNA ndicho chishandiso chokuchengeta mashoko muzvinhu zvakasikwa—inogona kuchengeta mashoko akawanda zvikuru mumorekuru duku uye yakatsiga zvikuru, ichirarama kwezviuru zvemakore mumamiriro ezvinhu akakodzera. Munguva pfupi yapfuura, masayendisiti akaongorora kugona uku nekunyora data muDNA pamuromo wepenzura, mumagaba ependi yekupfapfaidza, uye kunyangwe nekuviga data mumabhakitiriya mhenyu. Asi pane zvipingamupinyi pakushandisa DNA semutakuri weruzivo; kuverenga nekuinyora kunoramba kwakaoma uye kunononoka maitiro.
"Tichashandisa zano risingakwerete pfungwa kubva kubiology," anodaro Brian Cafferty, mumwe wevanyori vechidzidzo chitsva. "Panzvimbo iyoyo, isu takavimba nehunyanzvi hwakajairika kune organic uye analytical chemistry uye takagadzira nzira inoshandisa madiki, akaderera-mamorekuru-uremu mamorekuru kuti encode ruzivo."
Panzvimbo yeDNA, vaongorori vakashandisa oligopeptides, mamorekuru madiki akaumbwa nenhamba dzakasiyana dzeamino acid. Hwaro hwenzvimbo nyowani yekuchengetera imicroplate - ndiro yesimbi ine 384 maseru madiki. Musanganiswa wakasiyana we oligopeptides unoiswa muchitokisi chimwe nechimwe kuti encode imwe byte yeruzivo.
Iyo nzira inobva pane bhinari system: kana imwe oligopeptide iripo, inoverengwa se 1, uye kana isiri, zvino se 0. Izvi zvinoreva kuti code iri musero rimwe nerimwe inogona kumiririra tsamba imwe kana imwe pixel yemufananidzo. Kiyi yekuziva kuti ndeipi oligopeptide iripo musero hukuru hwayo, hunogona kuwanikwa uchishandisa mass spectrometer.
Mukuedza kwavo, vatsvakurudzi vakakwanisa kunyora, kuchengetedza uye kuverenga 400 KB yeruzivo, kusanganisira chinyorwa chehurukuro, mufananidzo uye mufananidzo. Sekureva kwechikwata, avhareji yekumhanya yekunyora yaive sere bhiti pasekondi uye kumhanya kwekuverenga kwaive makumi maviri mabhiti pasekondi, nekurongeka kwe20%.
Masayendisiti anoti hurongwa hutsva hune zvakanakira zvakawanda. Oligopeptides inogona kugadzikana kwemazana kana zviuru zvemakore, ichiita kuti ive sarudzo yakanaka yekugara kwenguva refu yekuchengetedza data. Vanogona zvakare kuchengetedza data rakawanda munzvimbo diki yemuviri, ingatopfuura DNA. Nokudaro, zviri mukati meNew York Public Library zvinogona kuchengetedzwa mu teaspoon izere neprotein.
Iyo sisitimu inogona kushanda neakawanda mamorekuru uye inogona kunyora data nekukurumidza kupfuura yayo DNA-yakavakirwa vamwe, kunyangwe vaongorori vachibvuma kuti kuverenga kunogona kunonoka. Chero nzira, tekinoroji inogona kuvandudzwa mune ramangwana nemaitiro ari nani, sekushandisa inkjet anodhinda kurekodha data uye yakagadziridzwa ma spectrometers kuti aiverenge.
