Qhov feem ntau siv ntawm recombinant DNA yog nyob rau hauv cov kev tshawb fawb hauv paus, uas cov tshuab Nws yog ib qho tseem ceeb rau feem ntau tam sim no ua hauj lwm nyob rau hauv cov tshuaj lom thiab biomedical sciences. Recombinant DNA yog siv txhawm rau txheeb xyuas, daim ntawv qhia thiab kab ke cov noob, thiab txiav txim siab lawv txoj haujlwm.

Tseem yuav paub yog, dab tsi yog DNA technology siv rau?

DNA technology yog ua siv rau pab kuaj cov kab mob caj ces, xws li kab mob mob hlwb thiab Huntington's disease. Txij li cov kab mob no raug xa mus los ntawm ib tiam mus rau lwm tiam, cov neeg uas muaj cov kab mob no tuaj yeem txheeb xyuas tau (qee zaum txawm tias ua ntej yug) thiab kho ua ntej cov tsos mob tshwm sim.

Tsis tas li ntawd, dab tsi yog recombination ntawm DNA technology? Recombinant DNA Technology . Recombinant DNA Technology yog txhais los ntawm Encyclopedia Britannica li kev koom ua ke ntawm DNA molecules los ntawm cov kab mob sib txawv thiab muab tso rau hauv cov kab mob hauv lub cev los tsim cov kev sib txuas caj ces tshiab uas muaj txiaj ntsig rau kev tshawb fawb, tshuaj, kev ua liaj ua teb thiab kev lag luam.

Kuj Paub, cov piv txwv ntawm DNA technology yog dab tsi?

Piv txwv ntawm DNA technologies

  • DNA cloning. Hauv DNA cloning, cov kws tshawb fawb "clone" - ua ntau cov ntawv luam ntawm - DNA feem ntawm kev txaus siab, xws li cov noob.
  • Polymerase chain reaction (PCR).
  • Gel electrophoresis.
  • DNA sequence.

Vim li cas DNA cloning suav tias yog ib qho tseem ceeb thev naus laus zis?

DNA cloning tso cai rau ntau cov noob tau theej, uas tuaj yeem ua rau kev tsim khoom loj / sau cov khoom siv tau zoo. Cov kws tshawb fawb feem ntau siv plasmids ua tus vector los hloov cov noob tshiab rau hauv cov kab mob.
