Viruses are tiny packets of destruction, and there are more of them than any other biological entity on the planet. U-M Medical School takes a closer look at a virus that causes tumors in animals, preferably monkeys, called SV40. SV40 is a DNA virus that, in order to make more of itself, burrows into a cell and then into its nucleus, thereby infecting it. Chelsey Spriggs, Ph.D., assistant professor of Cell & Developmental Biology and Microbiology & Immunology at U-M Medical School, discusses SV40 and the researchers study this virus and relate it to viruses that cause cancer in humans
