Certain plant viruses such as rice dwarf virus, maize rough dwarf virus have double stranded RNA as genetic material.

Certain bacteriophages like ϕX174 virus and plant viruses such as curly top virus have single stranded DNA as genetic material.

Most of the bacteriophages and all living organisms have double stranded DNA as genetic material.

Viruses like TMV and many plant viruses and certain animal viruses like retroviruses have single stranded RNA as genetic material.
