What are the differences and similarities between the transforming genes of retroviruses and those of DNA tumor viruses?

#Unit 4. Cell Communication and Cell Signaling

The oncoproteins encoded by transducing retroviruses are derived from viral replication, whereas those encoded by DNA viruses are derived from normal cell proteins. Both types of viruses express oncoproteins from integrated genomes.
