Sebakeng sa lipatlisiso tsa saense, li-nucleoside tse fetotsoeng li hlahile e le lisebelisoa tse matla tse fanang ka melemo e mengata. Li-nucleoside tsena tse fetotsoeng ka lik'hemik'hale li bohlokoa mafapheng a fapaneng, ho kenyeletsoa biology ea limolek'hule, biochemistry le lipatlisiso tsa bongaka. Ka ho utloisisa melemo ea ho sebelisa li-nucleoside tse fetotsoeng, bafuputsi ba ka ntlafatsa lithuto tsa bona le ho fumana liphetho tse nepahetseng le tse tšepahalang.
Ntlafatso ea botsitso le Sebetsa
E 'ngoe ea melemo ea mantlha ea li-nucleoside tse fetotsoeng ke botsitso ba tsona bo ntlafalitsoeng. Li-nucleoside tsa setso li ka ba le tšekamelo ea ho senyeha, tse ka senyang botšepehi ba liphello tsa liteko. Leha ho le joalo, li-nucleoside tse fetotsoeng li etselitsoe hore li tsitse haholoanyane, ho netefatsa hore li lula li tiile nakong eohle ea liteko. Botsitso bona bo bohlokoa bakeng sa lits'ebetso tse joalo ka tatellano ea RNA le motsoako oa DNA, moo lintlha tse lumellanang le tse tšepahalang li leng bohlokoa haholo.
Ntlafatso ea ho lemoha le ho hlahloba
Li-nucleoside tse fetotsoeng le tsona li phetha karolo ea bohlokoa ho ntlafatseng ho lemoha le ho hlahloba li-nucleic acid. Li ka kenyelletsoa ho li-probes le li-primers, tse matlafatsang kutlo le ho nepahala ha litlhahlobo tse fapaneng. Mohlala, mekhoeng ea polymerase chain reaction (PCR), li-nucleoside tse fetotsoeng li ka thusa ho holisa tatellano e nepahetseng, e lebisang ho liphetho tse nepahetseng le tse ka hlahisoang hape. Sena se molemo ka ho khetheha lits'ebetsong tsa tlhahlobo, moo ho lemohuoang ka nepo ha liphatsa tsa lefutso ho hlokahalang.
Keketseho e Tlamang Kamano
Molemo o mong oa li-nucleoside tse fetotsoeng ke bokhoni ba tsona ba ho eketsa kamano e tlamang ea li-nucleic acid. Sena se bohlokoa haholo ho nts'etsopele ea li-agent tsa kalafo le li-molecular probes. Ka ho kenyelletsa li-nucleosides tse fetotsoeng, bafuputsi ba ka etsa limolek'hule tse tlamang ka katleho lipakaneng tsa bona, ho ntlafatsa katleho ea phekolo le lisebelisoa tsa ho hlahloba. Kamano ena e ntseng e eketseha e tlamang e ka lebisa ho phekolo e sebetsang haholoanyane le liphello tse ntlafetseng tsa mokuli.
Mefuta-futa ea Likopo
Ho feto-fetoha ha li-nucleoside tse fetotsoeng ho fetela ho mefuta e mengata ea ts'ebeliso. Li sebelisoa ho nts'etsopele ea lithethefatsi tse thibelang likokoana-hloko, moo li ka thibelang ho ikatisa ha liphatsa tsa lefutso tsa kokoana-hloko. Ho feta moo, li-nucleoside tse fetotsoeng li sebelisoa lithutong tsa epigenetic ho etsa lipatlisiso ka liphetoho ho DNA le RNA tse laolang polelo ea liphatsa tsa lefutso. Ho tenyetseha hona ho li etsa lisebelisoa tsa bohlokoa lipatlisisong tsa mantlha le lits'ebetsong tsa bongaka.
Ho matlafatsa Tšebelisano ea Lipatlisiso le Tšebelisano
Ho fana ka litaba tsa bohlokoa mabapi le melemo ea li-nucleoside tse fetotsoeng ho ka khothaletsa tšebelisano e kholo le tšebelisano-mmoho ka har'a sechaba sa mahlale. Ka ho arolelana litsebo le tsoelo-pele, bafuputsi ba ka ithuta ho tsoa ho ba bang 'me ba ikahela holim'a tsebo e teng. Lipuisano tse khothatsang le maikutlo ka li-blog, liforamu, le mecha ea litaba ea sechaba li ka theha tikoloho ea lipatlisiso e matla le e tšehetsang. Sena ha se ntlafatse boleng ba lipatlisiso feela empa hape se matlafatsa maqhama ka har'a sechaba sa mahlale.
Qetello
Li-nucleoside tse fetotsoeng li fana ka melemo e mengata e ntlafatsang haholo lipatlisiso tsa saense. Ho tloha ho botsitso bo ntlafetseng le ho lemoha ho ea ho ho eketseha ha kamano e tlamang le ho feto-fetoha ha maemo, limolek'hule tsena li bohlokoa haholo lits'ebetsong tse fapaneng. Ka ho utloisisa le ho sebelisa melemo ea li-nucleoside tse fetotsoeng, bafuputsi ba ka fumana liphetho tse nepahetseng le tse nang le tšusumetso. Ho arolelana tsebo ena le ho khothaletsa tšebelisano-'moho ho ka ntšetsa pele tšimo, ho lebisa ho litšibollo tse ncha le liphetho tse ntlafalitsoeng liphuputsong tsa mahlale.
