Gene cloning tsim cov ntawv luam ntawm cov noob lossis ntu ntawm DNA. Kev yug me nyuam cloning tsim cov ntawv luam ntawm tag nrho cov tsiaj. Kev kho mob cloning tsim cov embryonic qia hlwb rau kev sim tsim cov ntaub so ntswg los hloov cov ntaub so ntswg raug mob los yog kab mob.
Piv txwv li, kev siv cloning yog dab tsi?
Cloning hlwb rau cov kab mob kho tsis tau Ib hnub, cov kws tshawb fawb vam tias cloned cov hlwb yuav raug siv los kho cov kab mob loj xws li teeb meem plawv, ntshav qab zib thiab raug mob qaum. Cov kws tshawb fawb vam tias yuav tshem cov qia hlwb los ntawm tsib hnub qub cloned embryo thiab loj hlob cov kab mob tshwj xeeb los ntawm lawv uas tuaj yeem kho tus kab mob.
Qhov thib ob, cov txheej txheem dab tsi yuav siv los clone tib neeg? Cloning siv somatic cell nuclear hloov chaw (SCNT) [1]. Qhov no txheej txheem pib nrog kev tshem tawm ntawm chromosomes los ntawm lub qe los tsim ib lub qe enucleated. Cov chromosomes yog hloov nrog ib tug nucleus coj los ntawm ib tug somatic (lub cev) cell ntawm tus neeg los yog embryo los ua. cloned.
Yog li ntawd, dab tsi yog qhov kev siv ntawm cloning tsiaj?
Daim ntawv thov uas tam sim no tab tom nrhiav suav nrog kev kho cov protein ntau hauv cov mis nyuj thiab cov ntshav ntawm transgenic cloned tsiaj , cov siv ntawm cov hlwb, cov ntaub so ntswg thiab lub cev los ntawm cov noob hloov tsiaj txhu rau kev hloov pauv mus rau tib neeg thiab hloov kho caj ces tsiaj txhu uas tsim cov khoom noj qab haus huv thiab kev nyab xeeb hauv ib qho
Yuav siv cloning li cas hauv tshuaj?
Tib neeg cloning ua tau siv los tsim cov embryos thaum ntxov, kos npe rau "cov kauj ruam tseem ceeb" rau tshuaj kho mob , hais US cov kws tshawb fawb. Cov cloned yog embryo siv raws li lub hauv paus ntawm cov qia hlwb, uas tuaj yeem ua rau lub plawv tshiab, cov pob txha, cov ntaub so ntswg los yog lwm yam cell hauv lub cev. Cloning bypasses qhov teeb meem no.

Vim li cas peb ntsuas qee qhov kev ncua deb hauv astronomy hauv lub teeb xyoo thiab qee qhov hauv astronomical units?
Feem ntau cov khoom nyob rau hauv qhov chaw nyob deb li deb, hais tias siv ib tug kuj me me chav nyob deb, xws li ib tug astronomical unit, yog tsis siv. Hloov chaw, astronomers ntsuas qhov deb ntawm cov khoom uas nyob sab nraum peb lub hnub ci hauv lub teeb xyoo. Qhov ceev ntawm lub teeb yog kwv yees li 186,000 mais lossis 300,000 kilometers ib ob
Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Dab tsi yog cov reagents xav tau rau PCR thiab dab tsi yog qhov ua haujlwm ntawm txhua tus?
Muaj tsib yam tshuaj reagents, lossis cov khoom xyaw, siv hauv PCR: qauv DNA, PCR primers, nucleotides, PCR tsis thiab Taq polymerase. Primers feem ntau yog siv nyob rau hauv khub, thiab DNA ntawm ob lub primers yog amplified thaum lub sij hawm PCR cov tshuaj tiv thaiv
Henri Becquerel nrhiav tau dab tsi uas ua rau nws tau txais 1903 Nobel nqi zog Nws nrhiav tau dab tsi txog lub caij uranium?
Teb: Henri Becquerel tau txais ib nrab ntawm qhov khoom plig rau nws qhov kev tshawb pom ntawm cov hluav taws xob tsis zoo. Teb: Marie Curie tau kawm txog cov hluav taws xob ntawm tag nrho cov tebchaw uas muaj cov xov tooj cua paub, suav nrog uranium thiab thorium, uas nws tom qab pom kuj tseem muaj xov tooj cua
Dab tsi yog qhov txawv ntawm microevolution thiab macroevolution Dab tsi yog qee qhov piv txwv ntawm txhua tus?
Microevolution vs. Macroevolution. Piv txwv ntawm cov kev hloov microevolutionary no yuav suav nrog kev hloov ntawm hom xim lossis loj. Macroevolution, piv txwv li, yog siv los hais txog kev hloov pauv ntawm cov kab mob uas tseem ceeb txaus uas, dhau sijhawm, cov kab mob tshiab yuav raug suav tias yog hom tshiab nkaus xwb
