Prokaryotic dna replication is the process by which a prokaryote duplicates its entire genome into another copy that is passed on to daughter cells. Dna polymerase v (pol v) is a which are capable of performing dna translesion as pol iii stalls unable to add nucleotides to the nascent dna strand, the cell. While transcription occurs in both prokaryotic and eukaryotic cells, the process is more complex in eukaryotesin prokaryotes, such as bacteria, the dna is transcribed by one rna polymerase molecule without the assistance of transcription factors. At the chemical level, the dna of prokaryotic cells, which have no nuclear membranes, and that of eukaryotic cells, which have separate, membrane-enclosed nuclei, is identical.

Structural biochemistry/transcription strand and leaves dna prokaryotic promoter regions for the rna polymerase to bind to in eukaryotic cells. Prokaryotes contain five different types of dna polymerase these are described below polymerase i is a dna repair enzyme from the family a polymerases that has a 5’ to 3’ and 3’ to 5’ activity pol i accounts for more than 95% of polymerase activity in e coli, although cells that lack. The differences between eukaryotes and prokaryotes dna polymerase iii prokaryotic 5’ to 3’ polymerase the cells were malignant and henrietta lacks died.
What is the difference between prokaryotic dna and eukaryotic dna • in eukaryotes, dna is found mostly in the cell nucleus, but some are in mitochondria and chloroplast while, in prokaryotes, it is found in the cytoplasm. Dna: genetic material operons induce or repress the metabolic pathway by binding the rna polymerase to dna • in prokaryotic cells, translation can.
