RNA - nyob ntawm RNA replication yog txheej txheem tshwj xeeb tshwj xeeb rau RNA cov kab mob tab sis tsis yog cellular RNAs. Yuav luag tag nrho RNA Cov kab mob (tshwj tsis yog retroviruses) raug mob RNA - nyob ntawm RNA replication los ntawm tus kab mob-encoded RNA - nyob ntawm RNA polymerase (RdRP), uas tshwj xeeb replicates tus kab mob RNA genome.
Tib neeg kuj nug, puas yog siv RNA hauv kev rov ua dua?
Rov ua dua ntawm Viral RNA . RNA replication yog txuam nrog rau cov kab mob nuclear. Cyclization ntawm cov RNA yog yuav tsum tau rau rov ua dua . Ib ntus los ntawm thaj tsam 5' thiab 3' ntawm tus kab mob dengue RNA uas tsim ib tug xov tooj ntawm qia-loop lug thiab uas kuj cyclize lub RNA yog illustrated nyob rau hauv daim duab.
Ib yam li ntawd, qhov txawv ntawm DNA replication thiab RNA replication yog dab tsi? Transcription thiab DNA replication ob qho tib si koom nrog ua cov ntawv theej DNA hauv a cell. Transcription luam the DNA rau hauv RNA , thaum rov ua dua ua lwm daim ntawv DNA . Txawm tias DNA thiab RNA muaj qee yam tshuaj sib xws, txhua molecule ua tau txawv ua haujlwm hauv cov kab mob muaj sia.
Tsis tas li ntawd, dab tsi yog cov kauj ruam ntawm RNA replication?
RNA Kev sau ntawv Txheej Txheem: RNA kev sau ntawv txheej txheem tshwm sim nyob rau hauv peb theem: pib , sawb elongation , thiab kev txiav txim . Thawj theem tshwm sim thaum lub RNA Polymerase -Promoter Complex khi rau cov noob txhawb nqa hauv DNA. Qhov no tseem tso cai rau kev tshawb nrhiav qhov pib ua ntu zus rau lub RNA polymerase.
Dab tsi yog RNA hauv DNA replication?
DNA replication pib ntawm cov ntsiab lus tshwj xeeb, hu ua keeb kwm, qhov twg DNA ob helix yog tsis mob. Ib ntu luv ntawm RNA , hu ua primer, yog ces synthesized thiab ua raws li ib tug pib taw tes rau tshiab DNA synthesis. Ib qho enzyme hu ua DNA polymerase tom ntej no pib replicating lub DNA los ntawm kev sib piv cov hauv paus rau qhov qub strand.

Dab tsi yog siv hauv DNA replication thiab protein synthesis?
Kev sau ntawv. Kev sau ntawv yog cov txheej txheem uas DNA tau theej (tshaj tawm) rau mRNA, uas nqa cov ntaub ntawv xav tau rau kev tsim cov protein. Kev hloov pauv yuav tshwm sim hauv ob kauj ruam dav. Ua ntej, ua ntej tus tub txib RNA yog tsim, nrog rau kev koom tes ntawm RNA polymerase enzymes
Lub luag haujlwm ntawm DNA polymerase hauv DNA replication Brainly yog dab tsi?
Kev piav qhia: DNA polymerase yog ib qho enzyme uas muaj ntau yam DNA polymerases. Cov no koom nrog hauv DNA replication, proofreading thiab kho DNA. Thaum lub sij hawm tus txheej txheem ntawm replication, DNA polymerase ntxiv nucleotides ntawm RNA primer
Dab tsi yog lub luag haujlwm ntawm DNA ligase hauv DNA replication?
DNA ligase yog ib qho enzyme uas kho irregularities los yog tawg nyob rau hauv lub caj qaum ntawm ob-stranded DNA molecules. Nws muaj peb lub luag haujlwm dav dav: Nws ntsaws ruaj ruaj hauv DNA, nws kaw cov khoom sib txuas ua ke, thiab nws txuas Okazaki fragments (cov DNA me me tau tsim thaum lub sij hawm rov ua dua ntawm ob-kab DNA)
Dab tsi yog qhov ua haujlwm ntawm enzyme topoisomerase hauv DNA replication quizlet?
Cais cov strands los ntawm kev paub lub hauv paus chiv keeb, rhuav tshem hydrogen bonds, thiab ua ib tug replication npuas. Lub hom phiaj ntawm topoisomerase yog dab tsi? unwinds lub resulting supercoils
Dab tsi yog replication hauv kev sim tsim?
Hauv engineering, science, thiab txheeb cais, kev rov ua dua yog qhov rov ua dua ntawm qhov kev sim ua kom qhov sib txawv ntawm qhov tshwm sim tuaj yeem kwv yees. ASTM, nyob rau hauv tus qauv E1847, txhais replication raws li 'repetition ntawm cov txheej txheem ntawm tag nrho cov kev kho mob ua ke yuav tsum tau muab piv rau hauv ib qho kev sim
