Yuav kom DNA molecules mus rau recombination, … ib ntawm ob DNA strands yuav tsum degraded.
DNA molecules tau txais kev sib txuas ua ke li cas?
Recombinant molecules nkag mus rau hauv cov hlwb nyob rau hauv cov txheej txheem hu ua transformation. Feem ntau, tsuas yog ib qho recombinant molecule yuav nkag mus rau ib tus neeg cov kab mob ntawm tes. Ib zaug nyob rau hauv, lub recombinant DNA molecule replicates zoo li lwm yam plasmid DNA molecule, thiab ntau daim ntawv yog tom qab tsim.
Yuav tsum tau ua dab tsi rau DNA recombinant?
Kev tsim ntawm DNA recombinant yuav tsum a cloning vector, DNA molecule uas replicates nyob rau hauv ib lub cell nyob. … Qhov kev xaiv ntawm vector rau molecular cloning nyob ntawm qhov kev xaiv ntawm cov kab mob hauv lub cev, qhov loj ntawm DNA yuav tsum tau cloned, thiab seb thiab yuav qhia txawv teb chaws DNA li cas.
DNA molecules recombinant yog dab tsi?
Recombinant DNA suav nrog molecules tsim tawm sab nraud ntawm cov cell nyob los ntawm kev koom nrog ntuj lossis hluavtaws DNA ntu rau DNA molecules uas tuaj yeem rov ua dua hauv lub cell nyob, lossis cov molecules uas tshwm sim los ntawm lawv cov replication.
Ib qho piv txwv ntawm DNA recombination yog dab tsi?
Piv txwv li, insulinyog ib txwm tsim los ntawm kev sib txuas DNA hauv cov kab mob. Tib neeg insulin noob tau nkag mus rau hauv plasmid, uas tom qab ntawd nkag mus rau cov kab mob ntawm tes. Cov kab mob ces yuav siv nws cov cellularmachinery los tsim cov protein insulin, uas tuaj yeem sau thiab faib rau cov neeg mob.

Pom zoo:
Yuav tau mus lossis yuav mus?
Went is the past tense of mus. Gone yog qhov kev koom tes yav dhau los ntawm kev mus. Yog tias koj tsis paub meej tias yuav siv ploj mus lossis mus, nco ntsoov tias ploj mus ib txwm xav tau cov lus qhia ua ntej nws (has, have, had, is, am, are, was, were, be), tab sis mus tsis tau.
Yuav ua li cas txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau pom kev pom?
Txawm li cas los xij, corneal collagen cross-linking - cov txheej txheem qib siab tau pom zoo los ntawm US Food and Drug Administration (FDA) hauv xyoo 2016 - tuaj yeem txhim kho qhov pom kev hauv cov neeg mob txhua hnub nyoog. Corneal collagen cross-linking (CXL) tsis yog kho rau keratoconus, tab sis nws tuaj yeem pab tiv thaiv tus mob kom tsis txhob mob hnyav.
Yuav ua li cas recombination ua rau variation?
Thaum meiosis, homologous chromosomes (1 ntawm txhua tus niam txiv) ua khub raws lawv qhov ntev. Chromosomes hla ntawm cov ntsiab lus hu ua chiasma. Ntawm txhua chiasma, cov chromosomes tawg thiab rov ua dua, ua lag luam qee yam ntawm lawv cov noob.
Vim li cas ho tsis ya mus rau sab hnub poob mus rau sab hnub poob tseem ceeb?
Southwest Airlines tau hais rau hnub Thursday nws yuav tsum tsis ua haujlwm hauv peb lub nroog, suav nrog Key West. "Hmoov tsis zoo,theem ntawm kev thov hauv zos tsis tso cai rau Southwest kom tau txais txiaj ntsig zoo rau cov lag luam no,"
Lub zog hloov pauv ntawm tiam mus rau kev xa mus rau kev faib tawm li cas?
Power, tshwj xeeb tshaj yog qib voltage, xa los ntawm cov kab xa tawm raug txo, lossis "tso nqis," los ntawm kev hloov pauv thiab xa mus los ntawm cov kab xa tawm, uas txuas nrog tom tsev thiab kev lag luam. … Nws yog ceg kawg ntawm kev xa hluav taws xob los ntawm ib tiam mus rau cov neeg siv khoom.
