DNA cloning yog siv tsim kom muaj ntau cov ntawv luam ntawm cov noob caj noob ces lossis lwm daim ntawm DNA . Cov cloned DNA tuaj yeem yog siv rau: Ua haujlwm tawm ntawm cov gene. Tshawb nrhiav cov yam ntxwv ntawm cov noob (qhov loj me, kev qhia, kev faib cov ntaub so ntswg)
Tsis tas li ntawd, lub hom phiaj ntawm cloning yog dab tsi?
Kev kho mob cloning koom nrog tsim ib cloned embryo rau ib leeg lub hom phiaj ntawm kev tsim cov embryonic qia hlwb nrog tib DNA raws li tus pub cell. Cov qia hlwb no tuaj yeem siv rau hauv kev sim ua kom nkag siab txog kab mob thiab tsim kho tshiab rau cov kab mob.
Ib sab saum toj no, DNA cloning ua haujlwm li cas? DNA cloning yog tus txheej txheem ntawm kev ua ntau yam, zoo tib yam luam ntawm ib daim ntawm DNA . Qhov ntxig yog ua tiav siv cov enzymes uas "txiav thiab muab tshuaj txhuam" DNA , thiab nws tsim ib tug molecule ntawm recombinant DNA , los yog DNA sib sau los ntawm cov khoom tawg los ntawm ntau qhov chaw.
Ib yam li ntawd, nws tau nug, dab tsi yog cov txiaj ntsig ntawm DNA cloning?
Ib qho tseem ceeb tshaj plaws pab ntawm DNA cloning thiab genetic engineering rau cell biology yog tias lawv tau ua kom tsim tau ib qho ntawm cov cell proteins nyob rau hauv ze li ntawm unlimited nyiaj. Cov protein ntau uas xav tau yog tsim nyob rau hauv lub hlwb los ntawm kev siv cov vectors (Daim duab 8-42).
Dab tsi yog ob txoj kev siv los clone DNA?
Muaj ob hom gene cloning : nyob rau hauv vivo, uas koom nrog kev siv cov kev txwv enzymes thiab ligases siv vectors thiab cloning cov fragments rau hauv host cells (raws li tau pom hauv daim duab saum toj no). Lwm hom yog nyob rau hauv vitro uas yog siv cov txheej txheem polymerase saw cov tshuaj tiv thaiv (PCR) los tsim cov ntawv luam ntawm cov khoom tawg. DNA.

Dab tsi ntawm pipette yog volumetric thiab nws siv rau dab tsi?
Lub volumetric pipette, noob pipette, lossis lub plab pipette tso cai rau kev ntsuas qhov tseeb (rau plaub qhov tseem ceeb) ntawm qhov ntim ntawm cov tshuaj. Volumetric pipettes feem ntau yog siv rau hauv analytical chemistry los ua cov kev daws teeb meem los ntawm lub hauv paus Tshuag thiab npaj cov kev daws teeb meem rau titration
Dab tsi yog kev siv cov saw hlau nuclear siv rau?
Nuclear chain reaction. Nuclear chain reactions yog cov tshuaj tiv thaiv uas tau txais lub zog nuclear, feem ntau los ntawm nuclear fission. Cov kev cuam tshuam ntawm cov saw hlau no yog qhov muab cov chaw tsim hluav taws xob nuclear nrog lub zog uas tom qab ntawd hloov mus ua hluav taws xob siv los ntawm tib neeg
Dab tsi yog gene cloning siv rau?
Gene cloning yog ib qho kev coj ua hauv molecular biology labs uas yog siv los ntawm cov kws tshawb fawb los tsim cov ntawv luam ntawm cov noob tshwj xeeb rau kev siv qis qis, xws li sequencing, mutagenesis, genotyping lossis heterologous qhia ntawm cov protein
Dab tsi yog qee qhov siv tau rau cloning?
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 lossis mob
Dab tsi yog qhov sib npaug siv los xam tag nrho cov khoom siv hluav taws xob siv?
Cov mis uas txuas lub zog thiab lub zog yog: Zog = Lub Zog x Sijhawm. Chav tsev ntawm lub zog yog joule, lub zog ntawm lub zog yog watt, thiab chav tsev ntawm lub sijhawm yog qhov thib ob
