Thaum lub sijhawm DNA rov ua dua, Okazaki tawg yog siv los ua kom ntev. … Lub lagging strand deb ntawm lub replication diav rawg replication diav rawg Lub replication diav rawg yog a qauv uas tsim nyob rau hauv lub 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

Vim li cas Okazaki fragments tsim thaum rov ua dua?
Okazaki fragments yog tsim rau ntawm lagging strand rau kev sib txuas ntawm DNA hauv 5′ rau 3′ kev taw qhia rau lub replication diav rawg. … Cov fragments muaj nyob raws li replication ntawm DNA tshwm sim nyob rau hauv lub 5′ -> 3′ kev taw qhia vim qhov kev txiav txim ntawm DNA polymerase ntawm 3′- OH ntawm tam sim no strand ntxiv dawb nucleotides.
Okazaki fragments elongate dab tsi?
Lub lagging strand deb ntawm kev sib hloov diav rawg. …
Puas Okazaki fragments ua thaum lub sij hawm replication?
Qeb luv luv ntawm DNA synthesized ntawm lub lagging strandthaum DNA rov ua dua. Thaum pib ntawm DNA replication, DNA unwinds thiab ob strands splits nyob rau hauv ob, ua ob "prongs" uas zoo li rab rawg (yog li, hu ua replication diav rawg).
Yuav ua li casOkazaki fragments thaum replication?
Thaum tus txheej txheem ntawm DNA replication, DNA thiab RNA primers raug tshem tawm los ntawm lub lagging strand ntawm DNA kom cia Okazaki fragments khi rau. … Rau Okazaki maturation tshwm sim, RNA primers yuav tsum tsim ntu ntawm cov fragments kom ligated. Qhov no yog siv los ua ib lub tsev thaiv rau kev sib txuas ntawm DNA nyob rau hauv lub lagging strand.
