Nucleic Acid Hybridization . Nucleic acid hybridization yog ib txoj kev siv los txheeb xyuas cov DNA ib ntus. Cov DNA tshwj xeeb sojntsuam yog denatured thiab annealed rau cov qauv DNA uas kuj tau denatured. Cov cheeb tsam luv luv ntawm lub hom phiaj DNA sib lawv liag tau sau npe thiab ua haujlwm raws li kev sojntsuam rau hybridization cov tshuaj tiv thaiv.
Tib neeg kuj nug, lub hom phiaj ntawm nucleic acid yog dab tsi?
Nucleic acid yog ib chav kawm tseem ceeb ntawm macromolecules muaj nyob hauv txhua lub hlwb thiab cov kab mob. Cov haujlwm ntawm nucleic acids yuav tsum ua nrog kev khaws cia thiab kev nthuav qhia ntawm cov ntaub ntawv caj ces. Deoxyribonucleic kua qaub (DNA) encodes cov ntaub ntawv uas lub cell xav tau los ua cov proteins.
Ib tug kuj yuav nug, dab tsi yog hybridization hauv biochemistry? Hauv molecular biology, hybridization (los yog hybridization ) yog ib qho tshwm sim uas ib leeg-stranded deoxyribonucleic acid (DNA) lossis ribonucleic acid (RNA) molecules anneal rau ntxiv DNA lossis RNA.
Thiab cov lus nug yog, dab tsi yog hybridization cov tshuaj tiv thaiv?
Cov hybridization cov tshuaj tiv thaiv yog tsim ntawm ib nrab los yog ua tiav ob-stranded nucleic acid molecules los ntawm kev sib txuas lus tshwj xeeb ntawm ob qho kev sib txuas ntawm ib leeg-stranded nucleic acids.
Thaum twg DNA hybridization nrhiav pom?
Kev tshaj tawm nyob rau lub caij ntuj sov xyoo 1960 (20) yog thawj zaug ua qauv qhia DNA -RNA hybridization txawm lub sij hawm ntawd tseem tsis tau muaj invented . Qhov tshwj xeeb ntawd hybridization tseem niaj hnub no dav siv nyob rau hauv uas immobilized oligo (dT) molecules yog siv los cais eukaryotic tub txib RNA los ntawm lawv cov poly (rA) tails.

Dab tsi yog ob lub hom phiaj tseem ceeb ntawm lub voj voog citric acid?
Ob lub hom phiaj tseem ceeb ntawm lub voj voog citric acid yog: A) synthesis ntawm citrate thiab gluconeogenesis. B) degradation ntawm acetyl-CoA los tsim lub zog thiab muab cov precursors rau anabolism
Dab tsi yog qhov txawv ntawm daim ntawv qhia lub hom phiaj thiab daim ntawv qhia lub hom phiaj tshwj xeeb?
Qhov tseem ceeb hauv daim ntawv qhia dav dav yog nyob ntawm qhov chaw. Phab ntsa daim duab qhia chaw, feem ntau daim ntawv qhia pom nyob rau hauv atlases, thiab txoj kev maps yog tag nrho cov nyob rau hauv qeb no. Thematic maps, tseem hu ua daim ntawv qhia tshwj xeeb, qhia txog thaj chaw faib khoom ntawm ib lub ntsiab lus lossis qhov tshwm sim
Dab tsi yog qhov flux los ntawm lub voos xwmfab ntawm sab yog tias tus nqi ntawm Q yog ntawm ib qho ntawm nws lub ces kaum?
Raws li peb paub tias, tag nrho cov flux los ntawm tus nqi q yog q / ε 0 (Gauss txoj cai). Yog hais tias tus nqi yog nyob rau ntawm lub ces kaum ntawm lub voos xwmfab, ib co ntawm cov flux nkag mus rau hauv lub voos xwmfab thiab tawm los ntawm ib co ntawm nws lub ntsej muag. Tab sis qee qhov flux tsis nkag mus rau hauv lub voos xwmfab. Qhov 1/8th no yuav muab faib ua 3 ntu dua
Dab tsi yog junk DNA thiab nws lub hom phiaj yog dab tsi?
Hauv cov noob caj noob ces, lo lus khib nyiab DNA hais txog thaj tsam ntawm DNA uas tsis yog coding. Qee qhov DNA noncoding no yog siv los tsim cov khoom tsis yog RNA xws li hloov RNA, tswj RNA thiab ribosomal RNA
Hom phiaj phiaj xwm phiaj xwm yog Mercator daim ntawv qhia?
Mercator projection. Mercator projection, hom phiaj xwm phiaj xwm qhia hauv 1569 los ntawm Gerardus Mercator. Nws yog feem ntau piav raws li ib tug cylindrical projection, tab sis nws yuav tsum tau muab los ntawm lej
