Qhov Tseem Ceeb Qhov txawv - Recombinant vs Nonrecombinant
DNA yog cov khoom siv caj ces ntawm yuav luag txhua yam kabmob. Nws yog tsim los ntawm nucleotides teem nyob rau hauv ntev chains. Muaj cov txheej txheem ntuj tsim thiab cov enzymes uas muaj peev xwm hloov cov nucleotide sequences thiab cov qauv ntawm DNA. Yog li, DNA feem ntau raug hloov pauv. Genetic recombination, uas tshwm sim thaum muaj kev sib deev, nws sib xyaw ob hom genomes. Genetic engineering yog ib qho kev siv thev naus laus zis hauv molecular biology uas hloov pauv cov genomes ntawm cov kab mob nrog txawv teb chaws DNA. Cov lus recombinant thiab nonrecombinant yog siv nyob rau hauv molecular biology los piav txog DNA. Recombinant DNA hais txog ib daim DNA uas sib txuas nrog lwm cov DNA txawv teb chaws los tsim cov DNA tshiab molecule. Nonrecombinant DNA yog hais txog niam txiv DNA lossis thawj DNA uas tsis muaj DNA txawv teb chaws. Qhov sib txawv tseem ceeb ntawm recombinant thiab nonrecombinant yog tias recombinant yog hais txog cov xwm txheej ntawm kev sib txuas ntawm ob lossis ntau hom DNA (tus kheej DNA thiab txawv teb chaws DNA) thaum nonrecombinant yog hais txog cov xwm txheej ntawm tsuas muaj DNA.
Recombinant yog dab tsi?
Lo lus recombinant yog hais txog DNA uas yog tsim los ntawm kev sib txuas DNA los ntawm ntau qhov chaw. Nws yog tshwm sim los ntawm kev sib txuas ntawm caj ces. Ob qhov sib txawv DNA sib xyaw ua ke los tsim cov DNA tshiab molecule uas tsis pom nyob rau hauv thawj genome. Nws yog lub npe hu ua recombinant DNA lossis chimeric DNA. Cov DNA txawv teb chaws tuaj yeem muab tso rau hauv lwm yam kab mob genome los tsim kom muaj DNA molecule recombinant. Kev tsim cov DNA recombinant yog ua los ntawm genetic engineering thiab recombinant DNA technology. Recombinant DNA yog tsim nyob rau hauv lub chaw soj nstuam los ntawm kev nqa cov khoom siv caj ces los ntawm ntau qhov chaw.
Nyob rau hauv molecular biology, cov noob xav tau rov ua dua nrog cov kab mob plasmids thiab nthuav tawm hauv cov kab mob. Cov txheej txheem no hu ua molecular cloning. Siv cov thev naus laus zis no, cov khoom lag luam muaj txiaj ntsig tau tsim nyob rau hauv loj. Cov proteins uas tshwm sim los ntawm kev qhia ntawm DNA recombinant hu ua recombinant proteins. Recombinant DNA muaj kev siv loj heev hauv biotechnology, tshuaj, kev tshawb fawb, kev lag luam, kev tsim khoom noj, tib neeg thiab veterinary tshuaj, kev ua liaj ua teb thiab bioengineering.
Daim duab 01: Recombinant DNA
Dab tsi yog kev sib koom ua ke?
Nonrecombinant yog hais txog qhov xwm txheej ntawm tsis qhia txog kev sib txuas ntawm caj ces. Nonrecombinant DNA zoo ib yam li cov niam txiv DNA. Cov xeeb leej xeeb ntxwv qhia zoo sib xws alleles kev npaj raws li nyob rau hauv thawj niam txiv DNA. Raws li pom nyob rau hauv daim duab 2, yog tias tsis muaj kev hla ntawm chromosomes thaum lub sij hawm ywj siab assortment, nonrecombinant DNA yuav yog qhov tshwm sim. Yog tias hla dhau tshwm sim, nws ua rau DNA rov ua dua. Qhov ua tau ntawm kev sib pauv chromatid yog qee yam ntawm cov caj ces recombination. Nws ua rau DNA uas txawv ntawm qhov qub DNA. Nonrecombinant DNA yog genetic tib yam nrog rau niam txiv hom.

Qhov txawv ntawm Recombinant thiab Nonrecombinant yog dab tsi?
Recombinant vs Nonrecombinant |
|
| Recombinant DNA yog ib daim DNA uas tau tsim los ntawm kev sib xyaw ua ke ntawm tsawg kawg ob kab. | Nonrecombinant yog DNA uas tsis tau raug tshuaj genetic recombination. |
| Yuav muaj kev nkag mus rau txawv teb chaws DNA rau hauv cov DNA recombinant. | Yuav tsis muaj DNA txawv teb chaws tso rau hauv cov DNA uas tsis sib txuas. |
| Similarity to Niam Txiv DNA | |
| Recombinant DNA txawv ntawm niam txiv DNA. | Nonrecombinant DNA yog tib yam li niam txiv DNA. |
| Kev hloov pauv caj ces | |
| Recombinant DNA qhia kev hloov pauv caj ces. | Nonrecombinant DNA tsis qhia kev hloov caj ces. |
Summary – Recombinant vs Nonrecombinant
Cov ntsiab lus recombinant thiab nonrecombinant piav qhia seb puas muaj caj ces recombination tau tshwm sim los yog tsis nyob rau hauv DNA sequences. Thaum DNA los ntawm ntau qhov chaw sib xyaw ua ke, thiab DNA tshiab tsim, nws yog hu ua recombinant DNA. Genetic recombination tsis tuaj yeem ua tau txhua lub sijhawm. Thaum nws caj ces recombination tsis tshwm sim, nws tsim nonrecombinant DNA. Nonrecombinant DNA qhia tau hais tias zoo ib yam genetic pleev rau niam txiv DNA. Qhov no yog qhov sib txawv ntawm recombinant thiab nonrecombinant DNA.
