In 1957, “Arthur Korenberg” showed that extracts of E.Coli contain a DNA polymerase (now called Polymerase I or Pol I ). In prokaryotes, DNA replication is the first step of cell division, which is primarily through binary fission or budding. Initiation : DNA replication initiate from specific sequences Origin of replication (ORI) called Replisoms.

Some DNA polymerase catalayze the synthesis of a DNA strand … Summary. Table 14.2 is useful. The number of DNA polymerases in eukaryotes is much more than in prokaryotes: 14 are known, of which five are known to have major roles during replication and have been well studied. Eukaryotes.
