Gene splicing yog ib qho kev hloov pauv hloov tom qab uas ib leeg noob muaj peev xwm code rau ntau yam proteins. Gene Splicing yog ua tiav hauv eukaryotes, ua ntej mRNA txhais lus, los ntawm qhov sib txawv ntawm kev suav nrog lossis tsis suav nrog thaj tsam ntawm pre-mRNA. Gene splicing yog qhov tseem ceeb ntawm cov protein ntau ntau.
Ntxiv mus, gene splicing pab tau li cas?
Gene splicing thev naus laus zis, yog li ntawd, tso cai rau cov kws tshawb fawb los ntxig cov tshiab noob rau hauv cov uas twb muaj lawm caj ces cov khoom ntawm cov kab mob genome kom tag nrho cov yam ntxwv, los ntawm cov kab mob tiv thaiv rau cov vitamins, thiab ua tau muab theej los ntawm ib lub cev thiab xa mus rau lwm tus.
Ib tug kuj yuav nug, ua li cas cov kws tshawb fawb splice noob? Hauv noob splicing , cov kws tshawb fawb noj ib qho kev txwv tshwj xeeb enzyme kom tshem tawm qee qhov strand lossis strands ntawm DNA. Nrog cov strands sib cais, cov kws tshawb fawb ntxiv qhov xav tau lub hauv paus khub rau cov DNA sib cais, hloov kho cov caj ces code ntawm DNA thiab yuav muab cov txheej txheem tshiab DNA rau cov kws tshawb fawb xav tau.
Tsis tas li ntawd, dab tsi yog splicing thiab vim li cas nws tseem ceeb?
Qhov tseem ceeb ntawm RNA splicing tsis to taub tag nrho, tab sis tus txheej txheem sawv cev ib tseem ceeb taw tes ntawm cov noob tswj, txij li feem ntau cov ntaub ntawv sau tseg tsis tuaj yeem tawm hauv lub nucleus los txhais kom txog thaum lawv cov introns raug tshem tawm. Qhov cuam tshuam ntawm splicing kuj yog tseem ceeb rau manipulation ntawm cov ntaub ntawv genetic.
Dab tsi tshwm sim hauv splicing?
RNA splicing yog kev tshem tawm ntawm introns thiab koom nrog exons hauv eukaryotic mRNA. Nws kuj tshwm sim hauv tRNA thiab rRNA. Splicing yog ua tiav nrog kev pab ntawm spliceosomes, uas tshem tawm introns los ntawm cov noob hauv RNA. Spliceosomes yog tsim los ntawm kev sib xyaw ntawm cov protein thiab me RNA molecules.

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 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
Dab tsi yog qhov tseem ceeb tshaj plaws uas yuav tsum muaj rau cov kua dej ntws hauv cov kav dej Dab tsi lwm yam cuam tshuam rau cov dej ntws?
Thaum ib qho kev quab yuam sab nraud yog exerted rau ntawm cov kua uas muaj, qhov tshwm sim siab yog kis sib npaug thoob plaws hauv cov kua. Yog li txhawm rau kom dej ntws, dej xav tau qhov sib txawv siab. Cov kav dej kuj tuaj yeem cuam tshuam los ntawm cov kua dej, cov yeeb nkab loj, qhov kub thiab txias (cov kav dej khov), cov kua dej ntom ntom
