Depending on the species, a virus can contain either DNA or RNA as its genetic material. Check out the Baltimore classification (https://en.wikipedia.org/wiki/Baltimore_classification) for more info.
> So there is research suggesting that viruses are actually a source of genetic material for humans.
They are! Endogenous retroviruses and the syncytin protein (involved in placental development) are some known examples.
