Kev txwv enzymes yog DNA txiav cov enzymes . DNA ligase yog DNA sib koom enzyme . Yog tias ob daim DNA muaj qhov sib txuam, ligase tuaj yeem txuas lawv los tsim ib qho, tsis tawg molecule ntawm DNA. Hauv DNA cloning, txwv enzymes thiab DNA ligase yog siv txhawm rau ntxig cov noob thiab lwm daim DNA rau hauv plasmids.

Tom qab ntawd, kev txwv enzymes siv hauv biotechnology li cas?

Kev txwv enzymes yog siv hauv biotechnology los txiav DNA rau hauv cov hlua me me txhawm rau kawm txog qhov sib txawv ntawm qhov sib txawv ntawm cov tib neeg. Qhov no yog hu ua txwv fragment ntev polymorphism (RFLP). Lawv kuj yog siv rau gene cloning. Kev paub txog cov chaw tshwj xeeb no yog lub hauv paus rau DNA ntiv tes.

Kuj Paub, kev txwv enzymes siv hauv tshuaj li cas? Kho mob Kev txhais ntawm Kev txwv enzyme . Kev txwv enzyme : Ib enzyme los ntawm cov kab mob uas tuaj yeem paub txog cov hauv paus hauv paus hauv DNA thiab txiav cov DNA ntawm qhov chaw ntawd (the txwv site). Kab mob siv txwv enzymes los tiv thaiv cov kab mob hu ua bacteriophages (los yog phage).

Tsis tas li lo lus nug yog, kev txwv enzymes thiab ligase siv nyob rau hauv recombinant DNA technology li cas?

Kev txwv enzymes yog cov enzymes uas tau txiav DNA . Koj tuaj yeem xav txog txwv enzymes raws li molecular txiab. DNA ligase yog ib enzyme uas tuaj yeem koom nrog ob DNA molecules. DNA ligase koom ob DNA molecules ua ke los ntawm kev tsim ib tug phosphodiester bond ntawm ob lub molecules.

Lub luag haujlwm ntawm ligase enzyme yog dab tsi?

DNA ligase yog ib enzyme uas kho irregularities los yog tawg nyob rau hauv lub caj qaum ntawm ob-stranded DNA molecules. Nws muaj qhov tseem ceeb luag hauj lwm nyob rau hauv cov txheej txheem ntawm DNA replication thiab kho DNA.
