sentences:  Ul12 and ICP8 viral proteins function together as a recombinase, possibly showing that while working with the host's recombination factors, work to form a concatemer by stimulating homologous recombination.These proteins may move the MRN complex towards the viral genome so it is able to promote homologous recombination, and to prevent non-homologous recombination as non-homologous recombination can have anti-viral effects.This possibly shows that the reaction between UL12 and MRN regulates the complex in a way that benefits the herpes virus.
