PowerPoint Presentation : 4/8/2013 DNA REPLICATION PART-II 28 DIFFERENCE IN PROKARYOTIC AND EUKARYOTIC REPLICATION As eukaryotic DNA is many times larger than prokaryotic DNA and is linear, there are multiple origins of replication ( Fig.3). SV40 T antigen binds and distorts the viral origin. In addition to replicative DNA polymerases for duplication of the leading and lagging DNA strands, another group of specialized polymerases is required for DNA repair and/or translesion DNA synthesis (TLS). The essential steps of replication are the same as in prokaryotes. - Viral Replication = spreading of a virus Viruses cannot replicate or express their genes without the help of a living cell. The practical applications of DNA technology affect our lives in many ways Many fields benefit from DNA technology and genetic ...

Before replication can start, the DNA has to be made available as a template. The chromatin (the complex between DNA and proteins) may undergo some chemical modifications, so that the DNA may be able to slide off the proteins or be accessible to the enzymes of the DNA replication machinery.

Since their genome is of the same molecular type (DNA) as their hosts genome, they can use the host cellular machinery for replication, transcription and translation.

Eukaryotic DNA Replication- Features, Enzymes, Process, Significance. Eukaryotic DNA replication Eukaryotic DNA replication is a conserved mechanism that restricts DNA replication to once per cell cycle. Eukaryotic DNA replication involves more polymerases than prokaryotic replication. Initiation : DNA replication initiate from specific sequences Origin of replication (ORI) called Replisoms.
