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.

Lub sijhawm sau ntawv rna polymerase transcribes?
Kev txhais lus pib thaum RNA polymerase khi rau qhov kev txhawb nqa ib ntus ze rau qhov pib ntawm cov noob (ncaj qha lossis los ntawm cov proteins pab). RNA polymerase siv ib qho ntawm cov DNA strands (cov qauv qauv strand template strand Los ntawm lub rooj sib tham, coding strand yog cov strand siv thaum tso saib DNA ib ntus.
Pyrimidine twg tsis muaj nyob hauv rna?
Pyrimidines suav nrog Thymine, Cytosine, thiab Uracil hauv paus uas tau hais los ntawm cov ntawv T, C, thiab U raws. Thymine muaj nyob hauv DNA tab sis tsis muaj nyob hauv RNA, thaum Uracil muaj nyob hauv RNA tab sis tsis nyob hauv DNA. Cytosine muaj nyob hauv DNA thiab RNA.
Vim li cas orcinol siv hauv kev kwv yees rna?
Cov orcinol reagent reacts nrog pentose pawg hauv cov pob txha ntawm RNA molecule thiab nyob ntawm qhov tsim ntawm furfural, thaum pentose yog rhuab nrog concentrated hydrochloric acid. Orcinol reacts nrog furfural nyob rau hauv lub xub ntiag ntawm ferric chloride ua ib tug catalyst muab ib tug ntsuab xim.
Puas yog tus kab mob marburg dna lossis rna?
Marburg tus kab mob (MVD) yog ib qho tsis tshua muaj tab sis mob hnyav heev uas cuam tshuam rau tib neeg thiab tsis yog tib neeg primates. MVD yog tshwm sim los ntawm tus kab mob Marburg, ib tug genetic cim zoonotic (los yog, tsiaj yug los) RNA virus ntawm tus kab mob filovirus Filovirus lub neej voj voog pib nrog virion txuas rau cov xov tooj ntawm tes-nto receptors, ua raws li kev sib xyaw ntawm lub hnab ntawv virion nrog cov cellular membranes thiab kev tso tawm ntawm tus
Puas yog rna polymerase muaj cov haujlwm ua pov thawj thaum lub sijhawm sau ntawv?
RNAP tsis tsuas yog pib RNA transcription, nws tseem coj cov nucleotides mus rau hauv txoj hauj lwm, txhawb kev txuas thiab elongation, muaj cov ntaub ntawv pov thawj hauv nruab nrab thiab hloov peev xwm, thiab kev paub txog kev txiav tawm. Hauv eukaryotes, RNAP tuaj yeem tsim cov saw hlau ntev li 2.
