Cov no cov enzymes yog tseem ceeb raws li lawv tso cai rau cov noob caj noob ces txiav tawm ntawm qhov chaw chromosome. Lawv kuj txiav kab mob plasmids . Siv cov tib yam txwv endonuclease enzyme rau txiav qhib lub plasmid raws li tau siv los txiav cov noob los ntawm cov chromosome ua rau ua tiav cov nplaum nplaum ua tiav.

Kuj tseem yuav paub yog, vim li cas nws tseem ceeb heev uas yuav tsum siv tib qho kev txwv enzyme ntawm ob lub plasmid thiab DNA?

Kev piav qhia: Kev txwv enzymes txiav ntawm ib ntus kom cov tib yam txwv enzyme yuav tsum tau siv vim nws yuav tsim fragments nrog cov ib yam complementary nplaum xaus, ua rau nws muaj peev xwm rau bonds tsim ntawm lawv. Lawv cov nplaum kawg sib phim, thiab yog li lawv tuaj yeem txuas ua ke.

Ib yam li ntawd, vim li cas peb thiaj txiav ob ntu ntawm DNA nrog tib qho kev txwv enzyme quizlet? Vim ob ntu ntawm DNA muaj cov ib yam paub qhov chaw ces lawv txiav los ntawm tib yam txwv enzyme . Yog txawv teb chaws DNA tuaj yeem pauv tau, ces cov hlwb hloov pauv tuaj yeem pauv tau.

Tsuas yog li ntawd, vim li cas nws tseem ceeb kom nrhiav tau ib qho enzyme uas yuav txiav?

Yog hais tias lub plasmid yog txiav ntawm replication, nws yuav tsis tuaj yeem tsim tawm & hloov cov ntaub ntawv caj ces rau nws lub xov tooj ntawm tes. 2. Nws yuav ua tawg tawg ntawm DNA thiab tsis muaj plasmid ntxiv yuav nyob rau hauv daim ntawv ncig.

Vim li cas tej zaum nws yuav yog ib qho tseem ceeb los txiav cov DNA strand kom ze rau cov noob xav tau li sai tau?

(Yuav kom paub tseeb tias cov xav tau Cov ntaub ntawv raug xa mus rau plasmid yam tsis tau ntxiv qhov tsis paub lossis tsis xav tau.) Hauv qhov haujlwm no, koj tau muab cov tshuaj insulin. noob nyob rau hauv lub plasmid.
