Ubuchwepheshe Bezinto Eziphilayo Nezokwelapha
Intuthuko kwezobuchwepheshe bezinto eziphilayo kanye nobezokwelapha ibe yizimbangela ezibalulekile zoshintsho ekhulwini lama-21. Azigcini nje ngokuthonya indlela ososayensi abaqonda ngayo impilo ezingeni lamaseli kanye nezakhi zofuzo, kodwa futhi ziguqula indlela abahlinzeki bezempilo abahlonza ngayo izifo, baklama izindlela zokwelapha, futhi bathuthukise ikhwalithi yokuphila. Kusukela emalabhorethri ocwaningo kuya emakamelweni okuhlinza, ubuchwepheshe besimanje bunikeza indlela enembile, esheshayo, neqondene nomuntu siqu. Lesi sihloko sihlola ububanzi, izibonelo zokusetshenziswa, izinzuzo, izinselele, kanye neziqondiso zesikhathi esizayo zobuchwepheshe bezinto eziphilayo kanye nobezokwelapha.
1. Incazelo kanye nobubanzi
Ubuchwepheshe bezinto eziphilayo buwukusetshenziswa kwesayensi yezinto eziphilayo ukukhiqiza imikhiqizo noma izinqubo eziwusizo. Ububanzi bayo bubanzi: i-biotechnology, ubunjiniyela bezakhi zofuzo, i-microbiology esetshenzisiwe, i-bioinformatics, kanye ne-bioprocesses yezimboni. Okwamanje, ubuchwepheshe bezokwelapha bugxile kumathuluzi, izindlela, kanye nezinhlelo zokuvimbela, ukuxilongwa, ukwelashwa, kanye nokuvuselelwa kwesiguli. Empeleni, lezi zinsimu ezimbili ziya ngokuya zihlangana. Izinto eziningi ezintsha zezokwelapha zivela ekuthuthukisweni kwe-biology yamangqamuzana, izakhi zofuzo, kanye nobuchwepheshe bekhompyutha.
Ukuhlanganiswa kwalokhu okubili kusobala ngokwemigomo efana nemithi enembile, ukwelashwa okusekelwe ku-gene, imithi yokugoma yesimanje, kanye namathuluzi okuxilonga asekelwe ku-biomarker. Ukubambisana kuzo zonke izinkambu—i-biology, imithi, i-chemistry, i-physics, ubunjiniyela, kanye nesayensi yedatha—kuyisihluthulelo sokuzalwa kwalezi zinto ezintsha.
2. Ubuchwepheshe Bezakhi Zofuzo kanye Nobunjiniyela Bezakhi Zofuzo
Esinye sezigaba ezibaluleke kakhulu ku-biology yanamuhla yikhono lokufunda nokushintsha izinto zofuzo. Ubuchwepheshe bokulandelana kwe-DNA buvumela ososayensi ukuthi babhale izakhi zofuzo ngokushesha nangokungabizi kakhulu ngezinga elikhulu. Lokhu kunemiphumela ebalulekile empilweni: izifo zofuzo zingatholakala kusenesikhathi, futhi izingozi zofuzo zingatholakala ngokuhlolwa kwezakhi zofuzo.
Ngaphezu kokufunda izakhi zofuzo, abantu manje sebeyakwazi nokuzihlela. Enye yezindlela zobuchwepheshe ezaziwa kakhulu yi-CRISPR-Cas9, "isikelo sama-molecule" esingasika i-DNA ezindaweni ezithile. Ngale ndlela, ezinye izifo ezizuzwe njengefa zinamandla okulungiswa ezingeni lezakhi zofuzo, yize ukusetshenziswa kwazo emtholampilo kusadinga ukuqaphela okukhulu. Ubunjiniyela bezakhi zofuzo bubalulekile nasekukhiqizweni kwemithi ye-biologic, njenge-insulin ephindaphindayo, i-hormone yokukhula, kanye nama-antibodies e-monoclonal.
Kodwa-ke, ukuhlela izakhi zofuzo kuveza inkinga yokuziphatha: ukuguqulwa kwezakhi zofuzo kufanele kuhambe ibanga elingakanani? Ingabe kungokwelapheka izifo kuphela, noma futhi "kungokwenyusa" amakhono abantu? Ngakho-ke, imithethonqubo kanye nengxoxo yomphakathi kuzobaluleka njengoba lobu buchwepheshe buthuthuka.
