Hauv SCNT lub nucleus, uas muaj cov kab mob DNA, ntawm ib lub cell somatic (ib lub cev cell uas tsis yog cov phev los yog qe cell) raug tshem tawm thiab lwm cov cell muab pov tseg. Ntawm Tib lub sijhawm, lub nucleus ntawm lub qe qe raug tshem tawm.
Tsis tas li ntawd, SCNT txheej txheem yog dab tsi?
Hauv genetics thiab kev loj hlob biology, somatic cell nuclear hloov ( SCNT ) yog ib lub tswv yim kuaj rau kev tsim cov embryo siv tau los ntawm lub cev thiab lub qe qe. Cov txheej txheem muaj xws li noj ib qho enucleated oocyte (qe cell) thiab implanting ib tug pub nucleus los ntawm ib tug somatic (lub cev) cell.
Ib yam li ntawd, thaum lub qe qe muaj nws cov nucleus tshem tawm thiab ib qho tshiab tso nws nkag mus rau txheej txheem hu ua? Somatic nuclear cell hloov (kuj hu ua kho cloning) koom nrog kev tshem tawm ib oocyte nucleus thiab nws hloov nrog a nucleus muab tau los ntawm ib tug somatic cell tau los ntawm tus zoo [79, 80].
Ib yam li ntawd, koj tuaj yeem nug, vim li cas somatic cell nuclear hloov pauv tseem ceeb?
Somatic cell nuclear hloov kev tshawb fawb yog ib tseem ceeb subset ntawm qia cell kev tshawb fawb thiab tuaj yeem tso cai rau cov kws tshawb fawb los tsim cov qia cell Cov kev kho mob uas tshwj xeeb raug kho raws li tus neeg mob tus mob thiab uas tsis ua rau lub cev tsis muaj zog.
Yuav ua li cas somatic cell nuclear hloov SCNT txawv ntawm txoj kev ua ib tug embryo?
Ntuj fertilization, qhov twg qe thiab phev koom, thiab SCNT ob leeg ua tib yam: ib lub pob faib ntawm hlwb , npe a lub embryo . Yog li cas tiag yog tus txawv ntawm ob? Ib cov embryo txhua tus muaj ob pawg ua tiav ntawm chromosomes.

Yuav ua li cas tshwm sim thaum magma txias thaum lub sij hawm lub pob zeb quizlet?
Raws li cov magma cools, loj thiab loj muaju tsim raws li lub pob zeb hardens. Yog tias magma tawm hauv lub ntiaj teb, lub pob zeb molten tam sim no hu ua lava. Thaum cov lava no txias rau ntawm lub ntiaj teb saum npoo, nws tsim cov pob zeb extrusive igneous. Lava txias sai heev, yog li cov pob zeb extrusive igneous tsis muaj crystals zoo
Yuav ua li cas koj paub thaum twg yuav siv cov khoom los yog quotient txoj cai?
Kev faib ua haujlwm. Yog li, thaum twg koj pom kev sib faib ntawm ob txoj haujlwm, siv txoj cai khoom thiab nyob rau hauv rooj plaub ntawm kev faib siv txoj cai quotient. Yog tias muaj nuj nqi muaj ob qho kev sib faib thiab faib, tsuas yog siv ob txoj cai raws li. Yog tias koj pom qhov sib npaug dav nws yog ib yam zoo li, qhov twg yog qhov ua haujlwm ntawm ib leeg
Yuav ua li cas cov thawj windings txuas thaum lub transformer yuav tsum tau ua nyob rau hauv ib tug 480 volt system?
Lub transformer muaj qhov polarity rho tawm thaum lub davhlau ya nyob twg H1 nyob ib sab ntawm lub davhlau ya nyob twg X1. Thaum lub 240/480 volt dual thawj tswj transformer yuav tsum tau ua los ntawm ib tug 240 volt system thawj winding yog kev cob cog rua nyob rau hauv parallel. Hauv Delta-connected transformer, theem thiab kab voltages sib npaug
Yuav ua li cas tshwm sim thaum tus txiv neej dig muag xim yuav ib tug poj niam ib txwm?
X qhia txog kev sib deev-txuas ntxiv cov noob rau xim dig muag. Yog hais tias tus txiv neej dig muag xim 0(Y) yuav poj niam ib txwm (XX), nyob rau hauv F1 tiam tag nrho cov txiv neej progeny (cov tub) yuav zoo li qub (XY). Cov poj niam progeny (cov ntxhais) tab sis yuav pom cov phenotype ib txwm, tab sis genetically lawv yuav heterozygous (XX)
Thaum twg koj yuav tsum siv correlation thiab thaum twg koj yuav tsum siv yooj yim linear regression?
Regression feem ntau yog siv los tsim cov qauv / qhov sib npaug los kwv yees cov lus teb tseem ceeb, Y, los ntawm cov txheej txheem kwv yees (X) sib txawv. Kev sib raug zoo feem ntau yog siv los ua kom sai thiab ua kom luv luv cov kev taw qhia thiab lub zog ntawm kev sib raug zoo ntawm ib pawg ntawm 2 lossis ntau tus lej sib txawv
