It detects and responds to a wide variety of pathogens, from viruses to … WebSome retroviruses have the ability to cause cancer because of the presence in the viral genome of an oncogene. When a proto-oncogene is mutated or aberrantly expressed it becomes an oncogene. E.g. The src gene encodes a protein kinase; overphosphorylation of the enzyme's substrates is a key process in the development of these tumors.
