Reverse transcriptase yog ib qho enzyme uas tsim los ntawm qee cov kab mob (retroviruses, uas khaws lawv cov ntaub ntawv caj ces li RNA tsis yog DNA), uas, raws li lub npe txhais, thim rov qab cov txheej txheem ntawm kev sau npe.
Cov piv txwv ntawm kev txwv enzymes yog dab tsi?
SmaI yog ib qho piv txwv ntawm kev txwv enzyme uas txiav ncaj qha los ntawm DNA strands, tsim DNA tawg nrog ib tug ca los yog blunt kawg. Lwm yam kev txwv enzymes, zoo li EcoRI, txiav los ntawm DNA strands ntawm nucleotides uas tsis yog sib txawv kiag li.
Peb hom kev txwv enzymes yog dab tsi?
Hnub no, cov kws tshawb fawb paub txog peb pawg ntawm kev txwv enzymes: hom I, uas paub txog cov DNA tshwj xeeb tab sis ua rau lawv txiav ntawm qhov chaw seem uas tuaj yeem ncav cuag 1,000 lub hauv paus khub deb ntawm qhov chaw lees paub; hom II, uas lees paub thiab txiav ncaj qha hauv qhov chaw lees paub; thiab type III,…
YPuas yog thim rov qab transcriptase A enzyme?
Reverse transcriptase yog ib qho enzyme uas tsim cov DNA siv RNA ua qauv.
Puas PCR siv txwv cov enzymes?
Kev txwv enzymes tuaj yeem siv siv los tsim kom muaj qhov kawg ntawm PCR cov khoom. Nyob rau hauv txhua rooj plaub, ib lossis ntau qhov txwv enzymes yog siv los zom cov DNA uas ua rau tsis muaj kev taw qhia lossis kev taw qhia nkag mus rau hauv cov plasmid sib xws.
