Replication diav rawg . Ib cheeb tsam Y-shaped ntawm a rov ua dua DNA molecule qhov twg cov strands tshiab loj tuaj. Koj nyuam qhuav kawm 18 nqe lus!
Tsuas yog li ntawd, replication fork txhais li cas?
Cov replication diav rawg yog thaj chaw nquag heev uas DNA rov ua dua siv qhov chaw. Nws yog tsim thaum DNA helicase unwinds ob helix qauv ntawm DNA. Cov replication diav rawg zoo li a diav rawg hauv txoj kev ntawd yog tsim los ntawm ib txoj hlua coj thiab ib txoj hlua khi ntawm DNA.
Ib tug kuj yuav nug, dab tsi yog cov kauj ruam ntawm DNA replication quizlet? DNA Replication pib ntawm keeb kwm ntawm Replication.
Yog li ntawd, dab tsi tshwm sim ntawm DNA replication fork quizlet?
Thaj chaw uas lub rov ua dua ntawm DNA yuav coj qhov chaw. Lub npe no yog muab vim hais tias ob strands uas unzipped zoo nkaus li zoo li ib tug diav rawg . Ib qho enzyme uas khi rau lub primer, thiab yuav ua rau ib txoj hlua tshiab DNA . Tsuas ntxiv DNA Base mus rau 5' kawg, mus rau 3' kawg.
Dab tsi strand yog synthesized ntawm replication fork quizlet?
Cov txoj hlua uas yog ua ke deb ntawm lub replication diav rawg , nyob rau hauv fragments siv seem hu ua Okazaki fragments. Cov tawg me me ntawm DNA ua rau ntawm kev lag luam txoj hlua thaum DNA rov ua dua , koom tom qab los ntawm DNA ligase rau tsim kom tiav txoj hlua.

DNA replication Quizlet yog dab tsi?
DNA replication yog tus txheej txheem ntawm tsim ob daim ntawv theej zoo tib yam ntawm DNA, nyob rau hauv uas txhua tus qauv rau kev sib txuas ntawm tus ntxhais tshiab strand. Cov primers yog synthesized los ntawm ib pawg ntawm cov proteins hu ua primosome, uas lub hauv paus tivthaiv yog ib tug enzyme primase, ib hom ntawm RNA polymerase
Replication thiab transcription yog dab tsi?
Transcription thiab DNA replication ob qho tib si koom nrog ua cov ntawv luam ntawm DNA hauv ib lub xovtooj. Cov ntawv luam theej theej DNA rau hauv RNA, thaum rov ua dua ua lwm daim qauv ntawm DNA. Txawm hais tias DNA thiab RNA muaj qee yam tshuaj zoo sib xws, txhua lub molecule ua haujlwm sib txawv hauv cov kabmob muaj sia
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
Dab tsi yog qhov yuav tsum tau rau DNA replication?
DNA tshiab yog tsim los ntawm enzymes hu ua DNA polymerases, uas yuav tsum tau ib tug template thiab ib tug primer (pib) thiab synthesize DNA nyob rau hauv lub 5' mus rau 3' kev taw qhia. DNA replication xav tau lwm yam enzymes ntxiv rau DNA polymerase, suav nrog DNA primase, DNA helicase, DNA ligase, thiab topoisomerase
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
