Explanation:
The advancement of biomedical research techniques and molecular biology has led to the observation of the close relationship between certain viruses and some cancers in various animals. Thus, it has been shown that several DNA and RNA viruses are oncogenic in a wide variety of animals, from amphibians to primates, and there is growing evidence that some human cancers have a viral origin.
Based on this, we can conclude that oncogenic viruses can be composed of DNA or RNA.
