DNA polymerases are enzymes that catalyze the template-directed synthesis of DNA. DNA dependent DNA polymerase Catalyzes DNA template directed extension of the 3’- end of a DNA strand . Cannot initiate a chain de novo. Requires a primer which may be DNA or RNA. RNA dependent DNA polymerase Reverse transcriptase Catalyzes RNA template directed Arthur Kornberg, who had a life-long love affair with enzymes, died on 26 October surrounded by his family and mourned by his extended family of students and colleagues. It is not surprising that only 2 weeks before, he had been actively summarizing decades of work on polyphosphate for a review structure. And while some DNA molecules are linear, others are circular. Still additional complexity comes from the supercoiling (further twisting) of the double helix, often around cores of DNA-binding proteins. Likewise, we now realize that RNA, which at first glance appears to be very similar to DNA, has its own distinctive structural features. University of Leicester – BS2009 – DNA Replication and Repair - 18 February 2010 Page 1 DNA Replication and Repair This lecture explores the mechanisms of DNA replication and also the ways in which DNA can repair any replication errors. It also looks at some of the causes of DNA damage and what failure of the repair mechanism can lead to. 1. The formation of nucleoprotein complexes between the Escherichia coli initiator protein DnaA and the replication origin oriC was analysed in vitro by band-shift assays and electron microscopy. DnaA protein binds equally well to linear and supercoiled oriC substrates as revealed by analysis of the

Endonucleases play a role in DNA repair. AP endonuclease, specifically, catalyzes the incision of DNA exclusively at AP sites, and therefore prepares DNA for subsequent excision, repair synthesis and DNA ligation.
