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 cov 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.

Raws li txoj cai, vim li cas nws tseem ceeb los tsim ib daim ntawv qhia kev txwv vector map?

Daim ntawv qhia ntawm DNA txwv sites yog ib tseem ceeb ib feem ntawm kev ua haujlwm hauv molecular biotechnology lab vim li ntawd daim ntawv qhia yog siv los npaj lub tswv yim cloning thiab xyuas seb thaum twg DNA clone tau ua tiav tiav. Cov ntaub ntawv no qhia tias txhua tus enzyme muaj ib leeg xwb txwv site nyob rau hauv plasmid.

Tsis tas li ntawd, daim ntawv qhia kev txwv qhia dab tsi? Daim ntawv qhia txwv . 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 cov 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.

Ntawm no, kev sib raug zoo ntawm qhov chaw txwv thiab daim ntawv qhia kev txwv yog dab tsi?

A daim ntawv qhia txwv qhia cov legnths ntawm DNA tawg nruab nrab ntawm qhov chaw txwv . Qhov ntau txwv qhov chaw muaj ntau qhov tawg yuav muaj nyob rau ntawm daim ntawv qhia.

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.
