A daim ntawv qhia txwv yog a daim ntawv qhia ntawm paub txwv cov chaw hauv ib ntu ntawm DNA. Kev txwv daim ntawv qhia xav tau kev siv txwv enzymes . Hauv molecular biology, txwv daim ntawv qhia yog siv los ua ib qho kev siv rau engineer plasmids lossis lwm yam luv luv ntawm DNA, thiab qee zaum ntev genomic DNA.

Tsis tas li ntawd, lub luag haujlwm ntawm daim ntawv qhia kev txwv yog dab tsi?

Kev txwv tsis pub tshaj tawm yog ib txoj hauv kev siv los qhia txog ntu tsis paub txog DNA los ntawm kev tawg mus rau hauv daim ntawv thiab tom qab ntawd txheeb xyuas qhov chaw ntawm qhov chaw tawg. Txoj kev no tso siab rau kev siv cov proteins hu ua txwv enzymes, uas tuaj yeem txiav, lossis zom, DNA molecules ntawm luv luv, tshwj xeeb ib ntus hu ua chaw txwv.

Dab tsi yog qhov chaw txwv ntawm plasmid? Qhov chaw txwv . Los ntawm Wikipedia, dawb encyclopedia. Qhov chaw txwv , los yog txwv kev paub qhov chaw , yog nyob rau ntawm DNA molecule uas muaj qhov tshwj xeeb (4-8 lub hauv paus khub hauv qhov ntev) ntawm nucleotides, uas tau lees paub los ntawm txwv enzymes.

Ib yam li ntawd, ib tug yuav nug, vim li cas kev txwv tsis pub daim phiaj xwm tseem ceeb?

Kev txwv daim ntawv qhia yog ib qho cuab yeej pab tau rau kev sim ua qhov kev sib sau ua ke tuaj yeem tawm ntawm pob nyiaj siv lossis tsis tsim nyog. Nws tuaj yeem siv los txiav txim seb lub noob tau cloned rau hauv plasmid. Nws yog cov txheej txheem zoo dua rau cov ntu luv ntawm DNA.

Dab tsi yog qhov txwv enzyme siv rau?

Hauv chav kuaj, txwv enzymes (los yog txwv endonucleases) yog siv rau txiav DNA rau hauv me me. Cov kev txiav yog ib txwm ua ntawm cov nucleotide ib ntus. txawv txwv enzymes lees paub thiab txiav cov DNA sib txawv.
