Do Retroviruses have RNA or DNA encoded in them

Retroviruses have RNA encoded in them. In fact retroviruses get their name just for the fact that they have double stranded RNA that is transcribed into DNA in order to infect a cell. HIV is an example of a Retrovirus.

And the retroviruses are included into the virus group ssRNA-RT viruses. They have single stranded(ss) RNA as the genetic code, and they retrotranscribe(RT) their RNA to DNA at first, and they have important vectors for gene therapy, as this DNA binds(integrates itself) into the host DNA, and alter its function. And from the retrotranscribed DNA, the virus codes the mRNA, then makes protein for itself.

Retroviruses are very valuable vectors for the therapy of genetically mutated patients, but the therapy has not been fully improved yet, but it is a great hope for these kind of patients.
