Cov khoom ntawm DNA lossis cov noob paj noob hlis yog txiav los ntawm nws qhov qub DNA uas siv cov enzyme txwv thiab tom qab ntawd muab tso rau hauv plasmid los ntawm ligation. Lub plasmid uas muaj cov DNA txawv teb chaws yog tam sim no npaj tau muab tso rau hauv kab mob . Cov txheej txheem no hu ua kev hloov pauv.
Tom qab ntawd, dab tsi yog cov kauj ruam ntawm kev hloov cov kab mob?
Ntsiab cov kauj ruam nyob rau hauv tus txheej txheem ntawm Cov kab mob hloov pauv : (1) muaj peev xwm npaj cell, (2) kev hloov pauv ntawm cell, (3) cell rov qab, thiab (4) cell plating.
Qhov thib ob, dab tsi yog tus neeg sawv cev ntawm kev hloov pauv hauv cov kab mob? Hauv kab mob , kev hloov pauv yog ua los ntawm kev sib xyaw transgenic DNA nrog kab mob hlwb tau kho kom lawv muaj peev xwm coj tau DNA. Ntau yam ntawm lwm txoj kev tau siv los qhia DNA rau hauv cov nroj tsuag thiab tsiaj txhu xws li DNA txhaj, electroporation, thiab microparticle bombardment.
Tus txheej txheem ntawm kev hloov pauv yog dab tsi?
Hauv molecular biology, kev hloov pauv yog qhov kev hloov pauv caj ces ntawm lub xovtooj ntawm tes uas tshwm sim los ntawm qhov ncaj qha uptake thiab kev koom ua ke ntawm exogenous genetic khoom los ntawm nws ib puag ncig los ntawm cov cell membrane (s).
Vim li cas cov kab mob hloov pauv tseem ceeb?
Taw qhia. Kev hloov pauv yog tus txheej txheem uas txawv teb chaws DNA nkag mus rau hauv ib lub cell. Kev hloov pauv ntawm kab mob nrog plasmids yog tseem ceeb tsis yog rau kev kawm hauv kab mob tab sis kuj vim kab mob yog siv los ua ib txoj hauv kev khaws cia thiab rov ua cov plasmids.

Cov kab lus hloov sab hauv cov ces kaum piav qhia txoj haujlwm ntawm ob lub kaum sab xis li cas?
Hloov sab hauv cov ces kaum yog tsim los ntawm ib tug transversal intersecting ob parallel kab. Lawv nyob nruab nrab ntawm ob qho tib si kab tab sis nyob rau sab nraud ntawm lub transversal, tsim ob khub (plaub tag nrho cov ces kaum) ntawm cov ces kaum sab hauv. Hloov cov ces kaum sab hauv yog congruent, txhais tau tias lawv muaj qhov sib npaug
Dab tsi tsim cov roj siab thiab nws hloov pauv li cas nrog kev hloov pauv hauv kinetic zog?
Gas siab yog tshwm sim los ntawm kev sib tsoo ntawm cov khoom siv roj nrog rau sab hauv ntawm lub thawv thaum lawv sib tsoo nrog thiab tawm dag zog rau ntawm phab ntsa ntim. Tom qab ntawd cov roj yog cua sov. Raws li qhov kub ntawm cov roj nce, cov khoom tau nce lub zog kinetic thiab lawv cov nrawm nrawm
Koj piav qhia txog kev hloov pauv li cas?
Kev hloov noob caj noob ces yog kev hloov pauv mus tas li hauv DNA ib ntus uas ua rau cov noob, xws li qhov sib txawv ntawm cov neeg feem coob. Kev hloov pauv ntau hauv qhov loj; lawv tuaj yeem cuam tshuam qhov twg los ntawm ib qho DNA tsev thaiv (hauv paus khub) mus rau ib ntu loj ntawm chromosome uas suav nrog ntau cov noob
Dab tsi yog cov kab mob piav qhia cov kab mob ntawm tes hauv kev nthuav dav?
Cov kab mob yog cov prokaryotes, tsis muaj cov nuclei zoo thiab cov kab mob sib txuas ua ke, thiab nrog cov chromosomes tsim los ntawm ib lub voj voog DNA kaw. Lawv tuaj nyob rau hauv ntau yam duab thiab ntau thiab tsawg, los ntawm feeb spheres, cylinders thiab kauv threads, rau flagellated rods, thiab filamentous chains
Koj piav qhia txog ib qho kev hloov pauv li cas?
VIDEO Ib yam li ntawd, tib neeg nug, koj piav qhia txog kev hloov pauv hauv lej li cas? Muaj plaub yam tseem ceeb ntawm kev hloov pauv : translation, rotation, reflection and dilation. Cov no kev hloov pauv poob rau hauv ob pawg: nruj kev hloov pauv uas tsis hloov cov duab lossis qhov loj ntawm qhov preimage thiab tsis nruj kev hloov pauv uas hloov qhov loj me tab sis tsis zoo li tus preimage.
