A txwv enzyme yog ib enzyme uas txiav DNA tom qab paub txog ib theem zuj zus ntawm DNA. Koj tuaj yeem xav txog txwv enzymes raws li molecular txiab. Cov kws tshawb fawb siv tau txwv enzymes txiav ib lub noob los ntawm ib qho loj ntawm DNA. Kev txwv enzymes evolved nyob rau hauv cov kab mob.

Ib yam li ntawd, tib neeg nug, lub luag haujlwm ntawm kev txwv enzyme yog dab tsi?

A txwv enzyme yog cov protein uas paub txog qhov tshwj xeeb, luv luv nucleotide ib ntus thiab txiav DNA tsuas yog ntawm qhov chaw tshwj xeeb, uas yog hu ua txwv qhov chaw los yog lub hom phiaj ib ntus. Hauv cov kab mob nyob, txwv enzymes ua haujlwm tiv thaiv lub cell tiv thaiv invading kab mob bacteriophages.

Tsis tas li ntawd, dab tsi yog lub hauv paus ntawm kev txwv enzymes? Cov kab mob yog cov loj qhov chaw ntawm kev lag luam txwv enzymes . Cov no cov enzymes pab tiv thaiv cov kab mob ntawm cov kab mob los ntawm kev ntxeem tau los ntawm txawv teb chaws DNA, xws li nucleic acid sequences siv los ntawm cov kab mob los replicate lawv tus kheej hauv ib lub cell.

Ib yam li ntawd, ob txoj haujlwm ntawm kev txwv enzymes yog dab tsi?

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 enzymes Kuj tseem siv tau los paub qhov txawv ntawm cov noob alleles los ntawm kev paub txog ib qho kev hloov pauv hauv DNA.

Kev txwv enzymes npe li cas?

Kev txwv enzymes muaj npe raws li cov kab mob uas lawv tau pom. Piv txwv li, lub enzyme Hind III raug cais tawm ntawm Haemophilus influenzae, strain Rd. Thawj peb tsab ntawv ntawm lub npe yog italicized vim lawv abbreviate lub genus thiab hom npe ntawm lub cev.
