Cov kev sib txuas ua ke yog sib xyaw ua ke raws li qhov kev txav ntawm kev sib txuas ntawm rab rawg replication diav rawg Qhov kev sib hloov diav rawg yog tus qauv uas tsim nyob rau hauv ntev helical DNA thaum lub sij hawm DNA replication Nws yog tsim los ntawm helicases, uas rhuav cov hydrogen bonds tuav ob DNA strands ua ke nyob rau hauv lub helix. Cov qauv tsim muaj ob ceg "prongs", txhua tus ua los ntawm ib txoj hlua ntawm DNA. https://en.wikipedia.org › wiki › DNA_replication
DNA replication - Wikipedia
thiab lub lagging strand yog synthesized nyob rau hauv opposite direction. … Cov strand yog synthesized nyob rau hauv luv luv fragments uas thaum kawg stitched ua ke, whereas lub lagging strand yog synthesized tsis tu ncua.
Yuav ua li cas rov sib txawv ntawm qhov kev coj thiab kev lag luam?
Ntawm ib rab diav rawg, ob qho tib si sib xyaw ua ke hauv 5′ → 3′ kev taw qhia. Cov kev sib txuas ua ke yog sib txuas txuas ntxiv, whereas lub lagging strand yog synthesized nyob rau hauv luv luv pieces hu ua Okazaki fragments.
Ua li cas cov thawj coj thiab cov lag luam sib txawv thaum lub sij hawm DNA replication quizlet?
cov strand yog synthesized tsis tu ncua thiab nyob rau hauv tib txoj kev raws lilub zog ntawm replication diav rawg, thaum lub lagging strand yog synthesized nyob rau hauv luv luv fragments uas thaum kawg stitched ua ke, nyob rau hauv qhov opposite direction.
Dab tsi yog qhov txawv ntawm txoj hlua khi thiab cov hlua khi hauv DNA replication chegg?
Txoj kev coj ua yuav tsum muaj RNA primer, qhov lagging strand tsis. Lub strand yog synthesized tsis tu ncua nyob rau hauv lub 5'3 'kev taw qhia, thaum lub lagging strand yog synthesized discontinuously nyob rau hauv lub 5'+3' kev taw qhia Cov coj strand yog.
Qhov twg hauv qab no cais cov DNA strands thaum rov ua dua?
Replication Fork Formation: Ib rab diav rawg replication yog tsim los ntawm kev qhib lub hauv paus ntawm replication; helicase cais cov DNA strands.
