The differences between DNA replication in prokaryotic and eukaryotic cells is due to the location, complexity, and size of the cell.


Prokaryotic Cells

  • Occurs in the cytoplasm
  • There is a single origin of replication
  • DNA gyrase is needed
  • Replication is very rapid (Bacteria can take up to 40 minutes)
  • The Okazaki fragments are very long (1000-2000
    Nucleotides long)
  • Prokaryotic cells have circular DNA thus telomeres are not replicated.

Eukaryotic Cells

  • Occurs in the nucleus
  • There are multiple origins of replication
  • DNA gyrase is not needed
  • The Okazaki fragments are short
  • Eukaryotic cells have telomeres at the end of DNA thus they are replicated.
