Gusesengura ibitekerezo bitari byo mu bushakashatsi mu bya siyansi

Siyansi y'ubuzima ni siyansi karemano ishingiye ku bushakashatsi. Mu kinyejana gishize, abahanga mu bya siyansi bahishuye amategeko y'ibanze y'ubuzima, nk'imiterere ya ADN ifite helix ebyiri, uburyo bwo kugenzura ingirabuzimafatizo, imikorere ya poroteyine, ndetse n'inzira z'ibimenyetso by'uturemangingo, binyuze mu buryo bw'igerageza. Ariko, kubera ko siyansi y'ubuzima ishingiye cyane ku bushakashatsi, biroroshye kandi kubyara "amakosa y'ubuhanga" mu bushakashatsi - kwishingikiriza cyane cyangwa gukoresha nabi amakuru y'ubuhanga, mu gihe birengagiza ko hakenewe imiterere y'inyigisho, imbogamizi z'uburyo, n'ibitekerezo bikomeye. Uyu munsi, reka turebere hamwe amakosa menshi akunze kugaragara mu bushakashatsi bwa siyansi y'ubuzima:

Amakuru ni Ukuri: Gusobanukirwa byuzuye ibyavuye mu igerageza

Mu bushakashatsi ku binyabuzima bya molekile, amakuru y’igerageza akunze gufatwa nk’ibimenyetso by’ubudahangarwa. Abashakashatsi benshi bakunda kuzamura ibisubizo by’igerageza mu buryo butaziguye mu myanzuro y’igerageza. Ariko, ibisubizo by’igerageza akenshi bigirwaho ingaruka n’ibintu bitandukanye nko mu bihe by’igerageza, ubuziranenge bw’icyitegererezo, ubushobozi bwo kumenya, n’amakosa ya tekiniki. Ikunze kugaragara cyane ni ubwandu bwiza muri PCR y’ikigereranyo cya fluorescence. Bitewe n’umwanya muto n’imiterere y’igerageza muri laboratwari nyinshi z’ubushakashatsi, biroroshye gutera ubwandu bwa PCR mu mwuka. Ibi akenshi bituma ingero zanduye zigira agaciro ka Ct kari hasi cyane ugereranyije n’imimerere nyayo mu gihe cya PCR y’ikigereranyo cya fluorescence. Iyo ibisubizo bitari byo by’igerageza bikoreshejwe mu gusesengura nta kuvangura, bizatanga gusa imyanzuro itari yo. Mu ntangiriro z’ikinyejana cya 20, abahanga mu bya siyansi bavumbuye binyuze mu bushakashatsi ko nucleus y’akaremangingo irimo poroteyine nyinshi, mu gihe igice cya ADN ari kimwe kandi gisa n’aho gifite "amakuru make". Bityo, abantu benshi bafashe umwanzuro ko "amakuru ya genetiki agomba kuba ari muri poroteyine." Iki cyari "igitekerezo gifatika" gishingiye ku bunararibonye icyo gihe. Mu 1944, Oswald Avery yakoze ubushakashatsi bwinshi bufatika, ni bwo yabanje kugaragaza bwa mbere ko ari ADN, atari poroteyine, ari yo yari nyirabayazana w’umurage nyakuri. Ibi bizwi nk'aho ari umwimerere w’ibinyabuzima bya molekile. Ibi kandi bigaragaza ko nubwo siyansi y’ubuzima ari siyansi karemano ishingiye ku bushakashatsi, ubushakashatsi bwihariye bukunze kugabanywa n’ibintu bitandukanye nko gushushanya igerageza n’uburyo bwa tekiniki. Kwishingikiriza gusa ku bisubizo by’igerageza nta shingiro bifite bishobora gutuma ubushakashatsi bwa siyansi buyoberana byoroshye.

Guhuza: guhuza amakuru yo mu gace runaka n'imiterere rusange

Ingorane z'ibintu bibaho mu buzima zigaragaza ko umusaruro umwe w'igerageza akenshi ugaragaza gusa imimerere mu buryo runaka. Ariko abashakashatsi benshi bakunze gushyira mu buryo butunguranye ibintu byagaragaye mu murongo w'uturemangingo, ku kinyabuzima cy'icyitegererezo, cyangwa se mu itsinda ry'ingero cyangwa igerageza ku bantu bose cyangwa ku bundi bwoko. Imvugo ikunze kuvugwa muri laboratwari ni iyi: 'Nakoze neza ubushize, ariko sinashoboye kubigeraho kuri iyi nshuro.' Uru ni urugero rukunze kugaragara rwo gufata amakuru yo mu gace nk'icyitegererezo rusange. Mu gihe cyo gukora igerageza risubirwamo hamwe n'ingero nyinshi zitandukanye zo mu byiciro bitandukanye, iki kibazo gikunze kubaho. Abashakashatsi bashobora gutekereza ko bavumbuye "amategeko rusange", ariko mu by'ukuri, ni ukwibeshya gusa ku mimerere itandukanye y'igerageza ishingiye ku makuru. Ubu bwoko bwa 'kwibeshya kuri tekiniki' bwari busanzwe cyane mu bushakashatsi bwa mbere bwa chip ya gene, kandi ubu bunagaragara rimwe na rimwe mu ikoranabuhanga rigezweho nko gukurikirana ingirabuzima fatizo imwe.

Raporo zitoranijwe: kwerekana gusa amakuru ahuye n'ibyo witeze

Gutanga amakuru atoranijwe ni kimwe mu makosa akunze kugaragara ariko kandi ateye akaga mu bushakashatsi bwa biology ya molekile. Abashakashatsi bakunda kwirengagiza cyangwa gupfobya amakuru adahuye n'ibitekerezo, ahubwo bagatanga gusa ibisubizo by'ubushakashatsi "byagenze neza", bityo bagashyiraho imiterere y'ubushakashatsi ihamye ariko itandukanye. Iri naryo ni rimwe mu makosa akunze kugaragara abantu bakora mu bushakashatsi bwa siyansi bufatika. Bashyiraho ibisubizo byitezwe mu ntangiriro y'igerageza, kandi nyuma y'uko igerageza rirangiye, bibanda gusa ku byavuye mu bushakashatsi byujuje ibyo biteganijwe, kandi bagakuraho mu buryo butaziguye ibisubizo bidahuye n'ibyo biteganijwe nk' "amakosa yo kugerageza" cyangwa "amakosa yo gukora". Uku gusesengura amakuru atoranijwe bizatanga gusa ibisubizo bitari byo by'imitekerereze. Iyi gahunda ahanini si iy'ubushake, ahubwo ni imyitwarire y'abashakashatsi batazi, ariko akenshi itera ingaruka zikomeye kurushaho. Linus Pauling, wahawe igihembo cya Nobel, yigeze kwemera ko vitamine C nyinshi ishobora kuvura kanseri kandi "yagaragaje" iki gitekerezo binyuze mu makuru ya mbere y'igerageza. Ariko igerageza ryinshi ryakurikiyeho ryagaragaje ko ibi bisubizo bidahamye kandi bidashobora gusubirwamo. Hari n'igerageza rimwe rigaragaza ko vitamine C ishobora kubangamira uburyo busanzwe bwo kuvura. Ariko kugeza uyu munsi, hari umubare munini w’ibitangazamakuru byigenga bivuga ku makuru y’igerageza rya Nas Bowling kugira ngo biteze imbere inyigisho yiswe inyigisho y’uruhande rumwe yo kuvura kanseri ya Vc, bigira ingaruka zikomeye ku kuvura abarwayi ba kanseri.

Gusubira ku mwuka wo guharanira inyungu no kuwurenza

Ishingiro ry'ubumenyi bw'ubuzima ni siyansi karemano ishingiye ku bigeragezo. Igerageza rigomba gukoreshwa nk'igikoresho cyo kugenzura inyigisho, aho gukoreshwa nk'ishingiro ry'ubwenge mu gusimbuza isesengura ry'ibitekerezo. Amakosa yo mu bushakashatsi akunze kugaragara aturuka ku kwizera kw'abashakashatsi mu makuru y'igerageza no kutagira imitekerereze ihagije ku bitekerezo n'uburyo bwo gutekereza.
Igerageza ni ryo tegeko ryonyine rigena ukuri kw'inyigisho, ariko ntirishobora gusimbura imitekerereze y'abahanga. Iterambere ry'ubushakashatsi bwa siyansi ntirishingira gusa ku gukusanya amakuru, ahubwo rinashingira ku buyobozi bwumvikana n'ubwenge busobanutse neza. Mu rwego rw'ibinyabuzima biri gutera imbere vuba, ni ukurushaho kunoza imiterere y'igerageza, isesengura ryimbitse, n'imitekerereze ishingiye ku gusesengura ni byo bishobora gutuma twirinda kugwa mu mutego w'ubuhanga bwo gusesengura no kwerekeza ku bumenyi nyakuri bwa siyansi.
