1.** Describe how an enveloped virus accomplishes each of the following steps during the productive life cycle.

A. viral attachment or adsorption to the host cell (ans)

B. viral entry into the host cell (ans)

C. viral movement to the site of replication within the host cell (ans)

D. viral replication within the host cell (ans)

E. viral assembly or maturation within the host cell (ans)

F. viral release from the host cell (ans)

2. When a virus infects the body, the body responds by producing antibodies that coat the virion. Discuss briefly how this might offer protection to the body. (ans)

3. One of the experimental approaches to preventing viral infection is to use recombinant DNA technology to artificially synthesize the host cell receptor molecule to which a specific virus would normally attach and then therapeutically administer this receptor to people prior to viral exposure. Discuss briefly how this might offer protection to the body. (ans)

4. Why are viruses generally very specific as to the types of hosts, tissues, and cells they are able to infect? (ans)
