Genetics
Research reports from University of Alberta provide new insights into genetics
June 16th, 2009
According to recent research from Edmonton, Canada, "Poxviruses are subjected to extraordinarily high levels of genetic recombination during infection, although the enzymes catalyzing these reactions have never been identified. However, it is clear that virus-encoded DNA polymerases play some unknown yet critical role in virus recombination." "Using a novel, antiviral-drug-based strategy to dissect recombination and replication reactions, we now show that the 3'-to-5' proofreading exonuclease activity of the viral DNA polymerase plays a key role in promoting recombination reactions. Linear DNA substrates were prepared containing the dCMP analog cidofovir (CDV)...
