Yuav ua li cas DNA replication txawv hauv eukaryotes piv rau prokaryotes quizlet?
DNA replication txawv li cas hauv cov hlwb prokaryotic thiab eukaryotic hlwb? Hauv cov cell prokaryotic feem ntau, rov ua dua pib los ntawm ib qho taw tes, thiab nws txuas ntxiv mus rau ob qho kev qhia kom txog thaum tag nrho cov chromosome tau theej. Hauv cov hlwb eukaryotic, rov ua dua tuaj yeem pib ntau pua qhov chaw ntawm DNA molecule.
Vim li cas RNA koom ua ke rau hauv DNA molecule thaum DNA replication?
Nws yuav tsum muaj rau DNA replication vim cov enzymes uas catalyze cov txheej txheem no, DNA polymerases, tsuas yog ntxiv nucleotides tshiab rau ib tug uas twb muaj lawm strand ntawm DNA. … Cov RNA primers no tuaj yeem ua de novo.
