The difference between these three types of zebras is only about where do zebras live and the answer is that they live at different places. One type of zebra wants to live on mountains and is known as a mountain zebras. Second type lives on plain, grassy lands and is called as Burchell's zebras. Third type of these animals is better known as Grevy's zebras. These zebras are the largest of all three types of the species.
An oncovirus is a virus that can cause cancer. This term originated from studies of acutely transforming retroviruses in the 1950â60s, often called oncornaviruses to denote their RNA virus origin. It now refers to any virus with a DNA or RNA genome causing cancer and is synonymous with tumor virus or cancer virus..The vast majority of human and animal viruses do not cause cancer, probably because of longstanding co-evolution between the virus and its host.t now refers to any virus with a DNA or RNA genome causing cancer and is synonymous with tumor virus or cancer virus..

What makes them unique is that they do not contain the necessary materials to function on their own. They are forced to invade a host cell (can be plant, animal, or bacterial) in order to thrive and reproduce. There are several ways that a virus can cause cancer. Some viruses can cause chronic inflammation. The resulting inflammation causes increased cell division in the process of making cells to replace damaged cells. Whenever cells divide, there is a risk that a genetic mutation will take place.
