DNA viruses. Originally viruses were grouped and named according to the disease they cause, even if they are not closely related. For example Hepatitis A is an RNA virus and Hepatitis B is a DNA virus, but they both cause liver disease.Nowadays, however, viruses are grouped by their shared characteristics in much the same way as plants and animals are. All but one of the DNA virus families use double stranded DNA as their infectious 'code'.riginally viruses were grouped and named according to the disease they cause, even if they are not closely related. For example Hepatitis A is an RNA virus and Hepatitis B is a DNA virus, but they both cause liver disease.
DNA Viruses vs RNA Viruses. â¢ The major difference between these two types is that the RNA viruses have RNA in their genome while the DNA viruses have DNA in their genome. Both the DNA and RNA cannot be found in the same virus. â¢ RNA virus first adsorbs to the host cell surface.Then the attached virus fuses with the endosome membrane. Finally as a result of fusion of the viral, nucleocapsid is released into the cytoplasm.Unlike RNA viruses, DNA viruses pass their DNA into the nucleus of the host cell and not into the cytoplasm of the host cell. â¢ DNA polymerase enzyme is used in the replication process of DNA viruses.Since the DNA polymerase has a refining activity, the mutation level is lower in DNA viruses. RNA polymerase is used in RNA replication process of RNA viruses. The major difference between these two types is that the RNA viruses have RNA in their genome while the DNA viruses have DNA in their genome. Both the DNA and RNA cannot be found in the same virus. â¢ RNA virus first adsorbs to the host cell surface. Then the attached virus fuses with the endosome membrane.
