The primary effort has focused on replication of the SV 40 (Simian Virus 40) chromosome; these studies have progressed so rapidly in recent years that the SV40 chromosome now can be replicated in-vitro using only eight purified components from mammalian cells. Eukaryotic DNA replication is unidirectional.
The specific functions of these proteins are highly reminiscent of proteins required for replication of plasmids carrying “Ori.C”. The DNA molecules in eukaryotic cells are considerably larger than those in bacteria and are organized into complex nucleoprotein structure. There are Eukaryotic DNA Replication origins many choices for appropriate answers.
Mechanism of Eukaryotic DNA Replication:
There are three Eukaryotic DNA replication steps required to synthesize new DNA molecule.
This unusual enzyme contains a catalytic site that polymerizes deoxyribonucleotides directed by an RNA template as well as the RNA molecule that functions as that template.
