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

  1. 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.

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

  3. There is no difference between the transforming genes of retroviruses and DNA tumor viruses. Both types of viruses express oncoproteins from integrated genomes.

  4. The oncoproteins encoded by transducing retroviruses are derived from normal cell proteins, whereas those encoded by DNA viruses are required for viral replication. There is no similarities in both types of viruses.
