Recombinant DNA technology muaj kev siv rau kev noj qab haus huv thiab khoom noj khoom haus. Hauv tshuaj kho mob , yog siv tsim tshuaj cov khoom xws li tib neeg insulin. Tom qab ntawd cov noob txiav tawm yog muab tso rau hauv ib ncig ntawm cov kab mob DNA npe plasmid. Tom qab ntawd cov plasmid yog rov qhia rau hauv cov kab mob ntawm tes.
Ib yam li ntawd, dab tsi yog 3 kev siv ntawm DNA recombinant?
Recombinant DNA thev naus laus zis kuj tau ua pov thawj tseem ceeb rau kev tsim cov tshuaj tiv thaiv thiab kev kho cov protein xws li tib neeg insulin, interferon thiab tib neeg kev loj hlob hormone. Nws kuj yog siv los tsim cov txheej txheem txhaws rau kev kho mob haemophilia thiab hauv kev txhim kho kev kho noob.
Ib yam li ntawd, cov txheej txheem ntawm DNA recombinant yog dab tsi? Recombinant DNA (los yog rDNA ) yog tsim los ntawm kev sib txuas DNA los ntawm ob lossis ntau qhov chaw. Cov txheej txheem nyob ntawm qhov muaj peev xwm txiav thiab rov ua dua DNA molecules ntawm cov ntsiab lus uas tau txheeb xyuas los ntawm cov kab ke tshwj xeeb ntawm nucleotide hauv paus hu ua chaw txwv.
Ib yam li ntawd, tib neeg nug, DNA siv li cas hauv tshuaj?
Pharmaceuticals thiab Tshuaj DNA technology yog ua siv los pab kuaj cov kab mob caj ces, xws li kab mob mob qog nqaij hlav thiab Huntington's disease. Muaj ntau txoj kev uas DNA technology yog siv los ua cov tshuaj tiv thaiv, xws li hloov cov kab mob cov noob thiab ua cov proteins ntawm cov kab mob phem.
Dab tsi yog recombinant khoom?
Recombinant cov khoom . Recombinant yam cov khoom yog tsim nyob rau hauv ib lub laboratory siv recombinant tshuab. Cov no cov khoom tsis yog tsim los ntawm tib neeg cov ntshav. Recombinant cov khoom muab kev xaiv nyab xeeb dua li cov ntshav plasma cov khoom vim lawv zam tsis tau cov ntshav los ntawm cov kab mob sib kis.

Yuav ua li cas cov txheej txheem ntawm cell faib nyob rau hauv eukaryotes feem ntau zoo ib yam li cell faib nyob rau hauv prokaryotes?
Tsis zoo li eukaryotes, prokaryotes (uas suav nrog cov kab mob) tau txais ib hom kev faib cell hu ua binary fission. Hauv qee qhov, cov txheej txheem no zoo ib yam li mitosis; Nws yuav tsum tau rov ua dua ntawm cov cell chromosomes, cais ntawm cov theej DNA, thiab kev sib cais ntawm niam txiv cell cytoplasm
Yuav ua li cas rau lub zog nyob rau hauv ib tug endothermic cov tshuaj tiv thaiv?
Cov tshuaj tiv thaiv kab mob endothermic tshwm sim thaum lub zog siv los rhuav tshem cov ntawv cog lus hauv cov reactants ntau dua li lub zog muab tawm thaum cov ntawv cog lus tsim hauv cov khoom. Qhov no txhais tau hais tias tag nrho cov tshuaj tiv thaiv yuav siv lub zog, yog li ntawd muaj qhov kub thiab txias hauv ib puag ncig
Yuav ua li cas tshwm sim rau atoms nyob rau hauv cov tshuaj tiv thaiv raws li Dalton lub atomic txoj kev xav?
Dalton's Atomic Theory Tag nrho cov atoms ntawm ib lub caij yog tib yam. Cov atoms ntawm cov ntsiab lus sib txawv sib txawv hauv qhov loj thiab loj. Cov tshuaj yog tsim los ntawm kev sib txawv ntawm cov lej sib txawv ntawm cov atoms. Cov tshuaj tiv thaiv tshuaj ua rau muaj kev hloov pauv ntawm cov atoms hauv cov reactant thiab cov khoom sib txuas
Cov tshuaj tiv thaiv zoo li cas thaum cov tshuaj nkag mus rau hauv cov hlab ntsha?
Cov tshuaj tiv thaiv 'systemic' tshwm sim thaum cov tshuaj nkag mus rau hauv cov hlab ntsha los ntawm daim tawv nqaij, qhov muag, qhov ncauj, lossis lub ntsws
Puas yog cov ntsiab lus uas muaj cov tshuaj lom neeg zoo sib xws yuav pom nyob rau tib lub sijhawm lossis hauv tib pab pawg piav qhia koj cov lus teb?
Qhov no yog vim hais tias cov tshuaj muaj zog nyob ntawm tsis muaj valence electrons. Raws li nyob rau hauv ib pawg tag nrho cov ntsiab lus muaj tib yam tsis muaj valence electron uas yog vim li cas lawv muaj cov tshuaj zoo sib xws tab sis nyob rau hauv ib lub sij hawm tsis muaj valence electron sib txawv uas yog vim li cas lawv txawv nyob rau hauv chemical zog
