RNA-dependent RNA polymerase (RdRp) lossis RNA replicase yog an enzyme uas catalyzes replication ntawm RNA los ntawm RNA template. Tshwj xeeb, nws catalyzes synthesis ntawm RNA strand complementary rau ib tug muab RNA template.
Dab tsi yog qhov ua haujlwm ntawm RNA dependent RNA polymerase?
RNA dependent RNA polymerase (RdRp) yog ib qho ntawm ntau yam enzymes ntawm RNA cov kab mob uas yog indispensable rau replicating lub genome nrog rau kev nqa tawm transcription. Cov yam ntxwv tseem ceeb ntawm RdRps tau txais kev cawmdim, txawm tias muaj kev sib txawv hauv lawv cov kab ke.
RNA dependent polymerases yog dab tsi?
Reverse transcriptase (RT), tseem hu ua RNA-dependent DNA polymerase, yog DNA polymerase enzyme uas hloov RNA ib leeg rau hauv DNA. Cov enzyme no muaj peev xwm los ua ke ob lub helix DNA ib zaug RNA tau thim rov qab hauv thawj kauj ruam mus rau hauv ib leeg-strand DNA.
Puas tib neeg puas muaj RNA nyob ntawm RNA polymerase?
Cov ntsiab lus: Lub xub ntiag ntawm cov txheej txheem uas luam RNA rau hauv RNA, feem ntau cuam tshuam nrog ib qho enzyme hu ua RNA-dependent RNA polymerase, tsuas yog tau sau tseg hauv cov nroj tsuag thiab cov kab mob yooj yim, xws li raws li cov poov xab, thiab cuam tshuam rau kev tswj hwm ntawm cov txheej txheem tseem ceeb ntawm tes. …
Puas yog RNA nyob ntawm RNA polymerase xav tau primer?
RNA polymerase II, lub enzyme uas ua ke mRNA los ntawm DNA, tsis xav tau primer. Reverse transcriptases xav tau atRNA primer, thaum qhov yuav tsum tau sib txawv ntawm RNA nyob ntawm RNA polymerases ntawm RNA kab mob.
