DNA replication occurs differently in prokaryotes and eukaryotes. In prokaryotes, DNA replication occurs in the cytoplasm and produces longer Okazaki fragments at a faster speed than in eukaryotes, where replication is confined to the nucleus and requires histone modification for initiation.

19. Particulars Prokaryotic replication of DNA Eukaryotic replication of DNA
Location of replication Cytoplasm Nucleus
Length of Okazaki fragment About 1500-2000 bp About 100-200 bp
Speed of replication 1000-2000 bp/s 150-200 bp/s
Histone modification Lacks histone Required for initiation
