Reverse transcriptase (RT) enzymes luam RNA rau hauv DNA. Tsis zoo li ntau DNA polymerases, RT enzymes tsis muaj cov ntawv pov thawj uas kuaj xyuasrau qhov tsis raug hauv DNA tshiab.
Puas thim rov qab transcriptase muaj kev ua haujlwm kho?
Lub kaw lus muaj qhov hloov pauv ntawm Cas9 enzyme fused nrog lwm cov enzyme, hu ua thim rov qab transcriptase, thiab cov lus qhia tshwj xeeb tsim kho RNA, hu ua pegRNA. Cov tom kawg muaj qhov xav tau cov noob hloov kho thiab coj cov cuab yeej kho kom raug rau ib qho chaw tshwj xeeb hauv cell DNA.
Puas thim rov qab transcriptase xav tau kev sib koom ua ke?
2015. Kev sib cuam tshuam ntawm kev thim rov qab transcriptase thiab kev sib koom ua ke yog xav tau rau kev hloov pauv rov qab thaum HIV-1 rov ua dua.
Dab tsi yog qhov txawv ntawm kev thim rov qab transcriptase?
Dab tsi yog qhov tshwj xeeb ntawm kev thim rov qab transcriptase? DNA fragments nrog ib leeg-stranded xaus.
Dab tsi thim rov qab transcriptase ua rau DNA?
Reverse transcriptase, tseem hu ua RNA-directed DNA polymerase, ib qho enzyme encoded los ntawm cov khoom siv caj ces ntawm retroviruses uas catalyzes cov transcription ntawm retrovirus RNA (ribonucleic acid) rau hauv DNA (deoxyribonucleic. acid).

Qhov twg yog qhov laj thawj tseem ceeb rau kev thim rov qab / tig rov qab lub tswv yim?
Lub hom phiaj yog txo cov nqi, ua kom cov haujlwm ua haujlwm zoo, lossis ua kom cov nyiaj ntsuab ntws ruaj khov. Peb lub hom phiaj tseem ceeb ntawm kev thim rov qab yog: Txoj Cai Hloov Kho - Qhov no yog lub tswv yim tsim kho dua tshiab. Nws hu kom rov kho cov haujlwm kom tau nyiaj ntau dua lossis tau txais txiaj ntsig.
Puas thim rov qab transcriptase siv dna ua tus qauv?
Reverse transcriptase thawj zaug sau cov khoom sib txuas ntawm DNA los ua RNA: DNA hybrid. Tom ntej no, thim rov qab transcriptase los yog RNase H degrades RNA strand ntawm hybrid. Lub ib leeg-stranded DNA yog siv los ua tus qauv rau kev sib txuas ob-stranded DNA (cDNA).
Puas rov tuav pov hwm rov qab xav tau cov neeg tuav pov hwm rov qab?
Cov tuam txhab tuav pov hwm rov qab feem ntau yuav rov ua pov hwm lawv tus kheej, lub sij hawm hu ua retrocession. Ntau txoj cai tau nthuav tawm ntawm ntau tus neeg tuav pov hwm rov qab. Nyob rau hauv rooj plaub no, qhov kev sib pauv yuav koom nrog tus thawj coj rov tuav pov hwm uas yuav sib tham txog cov ntsiab lus ntawm txoj cai uas lwm tus neeg tuav pov hwm rov qab yuav koom nrog.
Daim ntawv pov thawj puas txhais tau tias koj tau ntawv pov thawj?
A daim ntawv pov thawj txoj haujlwm tsis ua rau daim ntawv pov thawj kev tshaj lij. Yog lawm, cov kev kawm uas koj kawm hauv daim ntawv pov thawj tuaj yeem pab koj npaj kom tau txais daim ntawv pov thawj kev ua haujlwm tshwj xeeb, tab sis kev tau txais daim ntawv pov thawj tsis zoo ib yam li tau txais ntawv pov thawj.
Puas yog daim ntawv pov thawj lossis ntawv pov thawj tus kws qhia davhlau?
Daim ntawv pov thawj yog qhov ua tau lees paub. Lawv zoo sib xws tab sis tsis zoo ib yam. Qhov tseeb, hais txog cov kws qhia dav hlau, FAA ditched Certificate / Certified adjective ntev dhau los. Tam sim no tsuas yog "tso cai" tus kws qhia.
