1) Lawv raug siv los pab kev tso cov noob rau hauv plasmid vectors thaum lub sij hawm gene cloning thiab protein ntau lawm thwmsim. 2) Kev txwv cov enzymes tuaj yeem siv los paub qhov txawv ntawm cov noob alleles los ntawm kev paub txog ib qho kev hloov pauv hauv DNA.

Ib yam li ntawd, nws raug nug, dab tsi yog cov haujlwm ntawm kev txwv enzymes?

Kev txwv cov enzymes yog cov enzymes cais tawm ntawm cov kab mob uas lees paub cov ntu tshwj xeeb hauv DNA thiab tom qab ntawd txiav cov DNA los tsim cov khoom tawg, hu ua txwv tawg. Kev txwv cov enzymes ua si ib qho tseem ceeb heev lub luag hauj lwm nyob rau hauv kev tsim kho ntawm recombinant DNA molecules, raws li tau ua nyob rau hauv gene cloning thwmsim.

Ib tug kuj yuav nug, dab tsi yog txoj haujlwm ntawm kev txwv endonucleases quizlet? lawv paub cov kab ke tshwj xeeb hauv DNA thiab tom qab ntawd txiav cov DNA thiab tom qab ntawd txiav cov DNA los tsim cov khoom tawg, hu ua txwv tawg.

Ib yam li ntawd, koj tuaj yeem nug, vim li cas peb thiaj siv 2 txwv enzymes?

Hom II txwv enzymes yog cov uas paub siv rau txhua hnub molecular biology daim ntaub ntawv xws li noob cloning thiab DNA fragmentation thiab tsom xam. Cov no cov enzymes cleave DNA ntawm qhov chaw ruaj khov nrog kev hwm rau lawv qhov kev lees paub ua ntu zus, tsim cov khoom siv rov ua dua tshiab thiab cov qauv gel electrophoresis sib txawv.

Lub luag haujlwm ntawm kev txwv enzymes hauv gel electrophoresis yog dab tsi?

Nqe lus piav qhia: Muaj ib qho enzyme , npe txwv enzyme , uas tuaj yeem txheeb xyuas qhov tshwj xeeb nucleotide ib ntus, hu ua txwv cov chaw, thiab ua haujlwm cleaving. Cov txheej txheem no cais cov khoom siv caj ces rau hauv cov khoom me me uas yuav muaj cov noob (cov) nyiam.
