Document Summary

Lecture 5: mmi 113 (sept 16/16) the nature of give of prion prions and examples. Describe the general structure of enveloped and naked viruses. Explain how a virus can be a cause of cancer. Discriminate between active, latent and chronic infections with virus.

Souvenir coat = phospholipid (= enveloped); only some do this. New viruses leave the host cell and drift, looking for their own host cells to infect, sometimes take a souvenir coat when they leave the host cell. Responsible for majority of visits to family physician. Many ways they can be transmitted from host to host.
