What is the difference between an RNA and DNA virus?

You can make viruses into two great categories: those that have RNA for their genetic information, ribonucleic acid; and those that have deoxyribonucleic acid, DNA, in their genetic information. HIV is an RNA virus. That too is not unique and wouldn't form the basis of a final definition for HIV, because many viruses have RNA as their genetic information. Influenza virus is an RNA virus. Polio is an RNA virus. We call the genetic information the genome of an organism, when it's the entire genetic information. The genome of HIV, packaged in the middle of the particle that we call a virus, is RNA.
