Correct Answer: The viral DNA polymerase
Description: Trisodium phosphonoformate (foscarnet) inhibits herpes simplex virus (HSV) replication. Foscarnet is a potent inhibitor of HSV-induced DNA polymerase, and has little effect on known cellular DNA polymerases. Herpesvirus mutants resistant to the drug arise easily. To a lesser extent, foscarnet also appears to inhibit the polymerase of hepatitis B virus and retroviruses. Combinations of antivirals, including foscarnet, are currently prescribed to increase the clinical usefulness of the drugs..
