Sekuyisikhathi eside sazi ukuthi kunamaqembu amaningana abacwaningi abavela emanyuvesi ahlukene azama ukuthuthukisa ubuchwepheshe obudingekayo ukuze abantu bathathe elinye igxathu ngentshisekelo yabo ekugcineni lonke ulwazi namuhla olukwazi ukukhiqiza futhi, ngoba lokhu, siyakudinga ukugcina idatha kuma-molecule e-DNA ngendlela eqinile. Okwamanje, njengoba uzokhumbula ngokuqinisekile, sekuzuziwe gcina i-GIF ngaphakathi kolwazi lofuzo ngenxa yokusetshenziswa kwendlela eyaziwayo I-CRISPR-Cas9.
Enye yentuthuko yakamuva eyenziwe ngabaphenyi emasontweni adlule isanda kuvezwa nge iphepha enyatheliswa yilabo abadumile njalo University of Washington. Kulo mbhalo, obhalwe futhi wakhishwa elinye lamaqembu abo akhiqiza kakhulu, sifunda ukuthi bakwazile Hack computer usebenzisa deoxyribonucleic acid, into okungekho muntu owayengacabanga ukuthi yayingenzeka.
Abaphenyi baseYunivesithi yaseWashington bayaphumelela ukukhwabanisa ikhompyutha besebenzisa i-molecule ye-DNA yokwenziwa
Ukungena emininingwaneni ethe xaxa, ngoba ukuphela kwesigaba esedlule kuzokushiya ungabandanga, phawula ukuthi leli qembu labaphenyi likwazile ngempela ukukwenza ukufaka uhlelo olubi noma I-malware ngaphakathi kocezu oluncane lwekhodi yokwenziwa kofuzo okuthi, njengelukuluku, njengomunye walabo ababhekele le phrojekthi abeke amazwana, iqembu lathenga esitolo esiku-inthanethi esilithumele ekhelini elizimele le-just Amadola ka-89.
Lapho le-DNA yokwenziwa ethengwe kwi-intanethi ifika kubanikazi bayo abasha, bekufanele basebenzise inqubo yabo entsha nendlela yokusebenza ukuthola i-malware eshiwo ngenhla ekulandelaneni kwe-DNA ukuze bakuthole kamuva Hack ngempumelelo ikhompyutha. Ngokusobala futhi njengoba sebekhulumile, zonke izinyathelo zalo msebenzi zizokhonjiswa ngesonto elizayo ngesikhathi sokugubha i- Uchungechunge lwezokuphepha lwase-Usenix okuzokwenzeka eVancouver (Canada).
$ 89 yanele ukuthi ukulandelana kwe-DNA okwenziwe kuthunyelwe ekhaya kuwe
Okwamanje uzibuza ukuthi kungenzeka kanjani lokhu. Ngokusobala nangokuya ngokwalokho okuvezwe yilabo abaphethe lo msebenzi wokuhlola, lo mbono uqukethe ukusebenzisa ngqo indlela iDNA eklanywe ngayo.
I-molecule ye-DNA yanoma yisiphi isidalwa esiphilayo yakhiwa yizinhlobo ezine zezisekelo ezine-nitrogen, ezaziwa kangcono ngokuthi 'izincwadi', A ye-adenine, G ye-guanine, T ye-thymine, ne-C ye-cytosine. Unalokhu engqondweni, vele ukutshele ukuthi ukuze ufake ikhodi kwisoftware enobungozi ososayensi benze ifayili le- ithebula lokulingana phakathi kwekhodi yezofuzo uqobo kanye nekhodi kanambambili yesoftware uqobo. Umphumela walokhu kwaba:
- A=00
- C=01
- G = 10
- T = 11
Ngenxa yale ndlela yokusebenzisa ikhodi evelayo ngemuva kokufaka amakhodi bekuyi- uchungechunge lwe-DNA olunezinhlamvu eziyi-176 kuphela.
Kuthatha kuphela izinhlamvu eziyi-176 ngaphakathi kochungechunge lwe-DNA ukugqekeza ikhompyutha
Lapho sebefake isoftware emgqeni we-DNA, lesi siqeshana safakwa kwikhompyutha evame ukusetshenziswa yi-University of Washington ukwenza i-DNA imali. Umphumela wephrojekthi, ngokwenza imali uchungechunge, kube ukuthi abacwaningi bakwazi ukungena kule mishini. Njengoba kunengqondo futhi kulindeleke, akunakwenzeka ukuthi ngeketanga lalolu hlobo othile angagenca ikhompyutha yakho ukude noma kunjalo, isivivinyo sokuqala sempumelelo sesivele senziwe futhi senziwa.
Ngenxa yale phrojekthi futhi banikezwa ubufakazi obukhulu bokushoda kokuphepha le khompyutha ebenakho, abacwaningi, kusengaphambili okusha ocwaningweni lwabo, baqala ukuhlola ukuphepha kwezinhlelo eziyishumi nantathu zezinhlelo ezisetshenziswa kakhulu lapho zilandelana ngamaketanga e-DNA kulolu hlobo lwe ilabhorethri. Umphumela walolu cwaningo kwaba ukuthi empeleni iningi linokukhubazeka okungaba khona kokuphepha lokho kufanele kuvuselelwe futhi kuhlolwe ngezikhathi ezithile.
