The goal of my research is to investigate the mechanism of DNA replication and repair in both eukaryotic and prokaryotic systems. I have been mainly involved in studying the interactions of different proteins with the ring shaped sliding clamps whose main function is to tether the DNA polymerases to DNA for highly processive synthesis. My interest has been to further the understanding of the regulation of the traffic flow of different polymerases on the clamps in prokaryotic and eukaryotic organisms
