WebViruses are involved in cancers because they can either carry a copy of one of these genes or can alter expression of the cell's copy of one of these genes. These are the oncogenic virus (otherwise known as oncoviruses or tumor viruses). To understand the discovery of cellular proto-oncogenes 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.
