What is the difference between prokaryotic and eukaryotic DNA replicaton?What is the difference between prokaryotic and eukaryotic DNA replicaton?
there is only one replication origin in prokaryotes

"Prokaryotic DNA is arranged in a circular shape, and there is only one replication origin when replication starts. By contrast, eukaryotic DNA is linear; it does not connect end to end to form a circle. When it is replicated, there are as many as 1000 replication origins. Despite these differences, however, the underlying process of replication is the same for both prokaryotic and eukaryotic DNA.

IN EUKARYOTES,THE MONOCISTRONIC STRUCTURAL GENES HAVE INTERRUPTED CODING SEQUENCE CALLED EXONS.
EXONS ARE INTERRUPTED BY INTRONS,WHICH DO NOT APPEAR IN MATURE RNA.TIS COMPLICATES THE PROCESS.
SO TO AVOID THESE COMPLICATICATION AN ADDITIONAL PROCESS OF SPLICING, CAPPING AND TAILING OCCURS.
THESE PROCESS DO NOT OCCUR IN PROKARYOTES.What is the difference between prokaryotic and eukaryotic DNA replicaton?
its a medical term search at www.wikipedia.com it will help u out! DeoxyriboNucleic Acid can be of two categories...but for furteher details just click the site and type DNA into it or prokaryotic and eukaryotic...ok! get it got it good
IN PROKARYOTIC DNA
there is only one replication origin site but there are many ori sites in eukaryotic dna
