A Southern blot yog ib txoj hauv kev siv hauv molecular biology txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau kuaj DNA. Southern blotting ua ke hloov pauv ntawm electrophoresis-sib cais DNA tawg mus rau lub lim membrane thiab tom qab nrhiav kom pom cov tawg los ntawm kev sojntsuam hybridization.
Raws li txoj cai blotting yog dab tsi?
Blotting cov txheej txheem yog cov kws tshawb fawb siv los cais cov hom molecules. Hauv cov hlwb, lawv muaj nyob ua ke. Blotting Feem ntau yog ua los ntawm kev cia cov khoom sib xyaw ntawm DNA, RNA lossis cov protein ntws los ntawm cov nplais ntawm gel.
Qhov thib ob, Northern thiab Southern blotting yog dab tsi? Northern blot yog ua kom pom ib qho RNA ib ntus. Southern blot yog ua kom paub txog DNA ib ntus. Yeej lawv yog cov txheej txheem tib lub hauv paus ntsiab lus nrog qhov sib txawv me ntsis vim muaj cov hom phiaj sib txawv.
Khaws qhov no hauv kev xav, vim li cas Southern blotting tseem ceeb?
Southern Blotting . Southern blotting yog tsim los nrhiav ib qhov sib lawv liag ntawm DNA nyob rau hauv ib tug complex sib tov. Piv txwv li, Southern Blotting tuaj yeem siv los nrhiav cov noob tshwj xeeb hauv ib qho genome tag nrho. Tus nqi ntawm DNA xav tau rau cov txheej txheem no yog nyob ntawm qhov loj thiab cov haujlwm tshwj xeeb ntawm kev sojntsuam.
Dab tsi yog qhov tseeb ntawm cov xwm txheej hauv Southern blotting?
Muaj plaub kauj ruam tseem ceeb hauv Southern blotting txheej txheem: Hauv thawj kauj ruam, qauv DNA tau tawg los yog zom rau hauv cov khoom me me uas siv cov enzyme txwv. Tom qab digestion, lub DNA fragments raug cais siv gel electrophoresis. Agarose gel feem ntau yog siv rau lub hom phiaj no.

Lub epicenter, epicenter (/ˈ?p?s?nt?r/) lossis epicentrum nyob rau hauv seismology yog lub ntsiab lus ntawm lub ntiaj teb nto ncaj qha saum lub hypocenter lossis tsom, qhov chaw uas av qeeg lossis tawg hauv av
Dab tsi yog qhov txawv ntawm kev nkag siab dav dav BSH thiab kev nkag siab nqaim NSH?
12) Dab tsi yog qhov txawv ntawm qhov dav-sensitive heritability (BSH) thiab nqaim-sense heritability (NSH)? A) BSH yog ib qho kev ntsuas ntawm cov noob uas cuam tshuam rau qhov zoo, thaum NSH yog ib qho kev ntsuas ntawm cov noob nrog cov teebmeem loj. B) NSH muaj feem xyuam rau ib leeg-gene yam nkaus xwb
Koj nkag siab dab tsi los ntawm qhov polar xwm ntawm dej?
Dej yog ib qho 'polar' molecule, txhais tau hais tias muaj kev faib tsis sib xws ntawm electron ceev. Dej muaj ib feem tsis zoo nqi () nyob ze ntawm cov pa atom vim cov unshared khub ntawm electrons, thiab ib nrab nqi zoo () nyob ze hydrogen atoms
Dab tsi yog txheej txheem spontaneous thiab non-spontaneous txheej txheem?
Cov txheej txheem spontaneous yog ib qho uas tshwm sim yam tsis muaj kev cuam tshuam ntawm sab nraud. Ib txoj kev uas tsis yog tshwm sim yuav tsis tshwm sim yog tias tsis muaj kev cuam tshuam ntawm sab nraud
Cov txheej txheem Southern blotting yog dab tsi?
Ib lub Southern blot yog ib txoj hauv kev siv hauv molecular biology txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau kuaj DNA. Yav qab teb blotting sib txuas cov kev hloov ntawm electrophoresis-sib cais DNA tawg mus rau ib lub lim membrane thiab tom qab fragment nrhiav tau los ntawm kev sojntsuam hybridization
