The DNA virus uses nucleus of the host to replicate it genetic material since it lack reverse transcriptase enzyme.The similarities between the DNA virus with human protein it make difficult to treat this virus without damaging the host cell.

RNA virus has reverse transcriptase enzyme which is used to replicate its genetic material, but it lack ability to check errors, which led to higher mutation rate.The transcriptase enzyme is used to make vaccine which is used to treat RNA virus
