Retroviruses are RNA viruses. Some of them are tumor inducing. They are binding on the cell's surface, than fused, and releasing RNA with polymerase, which is called in this case reverse transcriptase. It copies RNA to ssDNA (single stranded), and than to dsDNA (double stranded), which is then sent to nucleus to express viral genes. Ref.: Molecular Cell Biology by Lodish
