I kēia mau lā, hiki iā mākou ke ʻike i nā ʻike āpau o ke kanaka mai nā kamepiula liʻiliʻi i loko o kā mākou ʻeke. Pono e mālama ʻia kēia ʻikepili a pau ma kahi, akā lawe nā kikowaena nui i ka nui o ke kino a koi i ka ikehu. Ua hoʻomohala nā mea noiʻi ʻo Harvard i kahi ʻōnaehana hou no ka heluhelu ʻana a me ke kākau ʻana i ka ʻike me ka hoʻohana ʻana i nā molekala organik i hiki ke noho paʻa a hana no nā kaukani makahiki.
ʻIke maopopo ʻia ʻo DNA ka mea hana no ka mālama ʻana i ka ʻike i loko o ke ao kūlohelohe - hiki iā ia ke mālama i ka nui o ka ʻikepili i loko o kahi mole liʻiliʻi a paʻa loa, e ola ana no nā millennia i nā kūlana kūpono. I kēia mau lā, ua ʻimi ka poʻe ʻepekema i kēia mana ma o ka hoʻopaʻa ʻana i ka ʻikepili i loko o ka DNA ma ka piko o nā penikala, i loko o nā kini o ka pena ehu, a me ka hūnā ʻana i ka ʻikepili i loko o ka bacteria ola. Akā, aia nā pilikia i ka hoʻohana ʻana i ka DNA ma ke ʻano he mea lawe ʻike; ʻo ka heluhelu a me ke kākau ʻana he mea paʻakikī a lohi.
"E hoʻohana ana mākou i kahi hoʻolālā e hōʻaiʻē ʻole i nā manaʻo mai ka biology," wahi a Brian Cafferty, kekahi o nā mea kākau o ka noiʻi hou. "Ma ka mea, ua hilinaʻi mākou i nā ʻenehana maʻamau i ka kemika organik a me ka analytical a ua hoʻomohala i kahi ala e hoʻohana ai i nā molekala liʻiliʻi, haʻahaʻa-molecular-weight e hoʻopili ai i ka ʻike."
Ma kahi o DNA, ua hoʻohana nā mea noiʻi i nā oligopeptides, nā molekole liʻiliʻi i hana ʻia i nā helu like ʻole o nā waikawa amino. ʻO ke kumu no ka waihona waihona hou he microplate - he pā metala me 384 mau wahi liʻiliʻi. Hoʻokomo ʻia nā hui like ʻole o nā oligopeptides i kēlā me kēia cell e hoʻopili i hoʻokahi byte o ka ʻike.
Hoʻokumu ʻia ka mīkini ma kahi ʻōnaehana binary: inā loaʻa kahi oligopeptide, heluhelu ʻia ʻo ia ma ke ʻano he 1, a inā ʻaʻole, a laila e like me 0. ʻO ia hoʻi, hiki i ke code i kēlā me kēia cell ke hōʻike i hoʻokahi leka a i hoʻokahi pika o kahi kiʻi. ʻO ke kī i ka ʻike ʻana i ka oligopeptide i loko o ke kelepona ʻo ia kona nuipa, hiki ke loaʻa me ka hoʻohana ʻana i kahi spectrometer.
Ma kā lākou mau hoʻokolohua, hiki i nā mea noiʻi ke hoʻopaʻa, mālama a heluhelu i ka 400 KB o ka ʻike, me kahi palapala haʻiʻōlelo, kahi kiʻi a me kahi kiʻi. Wahi a ka hui, ʻo ka awelika o ke kākau ʻana he 20 bits i kekona a ʻo ka wikiwiki heluhelu he 99,9 bits i kekona, me ka pololei o XNUMX%.
Wahi a nā kānaka ʻepekema he nui nā pono o ka ʻōnaehana hou. Hiki i nā Oligopeptides ke paʻa no nā haneli a mau tausani makahiki, e hana ana iā lākou i koho kūpono no ka mālama ʻana i ka ʻikepili archival lōʻihi. Hiki iā lākou ke mālama i nā ʻikepili hou aʻe i kahi wahi kino liʻiliʻi, ʻoi aku paha ma mua o DNA. No laila, hiki ke mālama ʻia nā ʻike holoʻokoʻa o ka New York Public Library i loko o kahi teaspoon i piha i ka protein.
Hiki i ka ʻōnaehana ke hana me kahi ākea o nā molekala a hiki ke kākau i ka ʻikepili ma mua o kāna mau hoa pili DNA, ʻoiai ua ʻae ka poʻe noiʻi hiki ke lohi ka heluhelu. ʻO kēlā me kēia ʻaoʻao, hiki ke hoʻomaikaʻi ʻia ka ʻenehana i ka wā e hiki mai ana me nā ʻenehana ʻoi aku ka maikaʻi, e like me ka hoʻohana ʻana i nā mīkini paʻi inkjet e hoʻopaʻa i ka ʻikepili a me ka hoʻomaikaʻi ʻana i nā spectrometers lehulehu e heluhelu ai.
Ua paʻi ʻia ke aʻo ʻana ma kahi puke pai ʻepekema .
