1) You are exposed to influenza viruses, and alas, you have not yet had your influenza vaccine this year! Unfortunately, the viruses manage to bind successfully to epithelial cells in your nasal passageways, initiating an infection.

a) Follow the pathway of a single virus as it initiates its infection, resulting in the production of numerous virus particles.

b) Describe your immune system and its response: both innate (first line, that was breached, and second line of defense) and adaptive. Which components may not have played a role in protecting you, and which ones will ultimately hopefully clear this infection?

2) Consider a group of humans all exposed to pathogens (i.e., the same disease-causing organism, but presumably a population of such!) Examples might be a group of people eating at a restaurant, or all exposed to a respiratory pathogen in a shopping mall, classroom, or on an airplane, etc.

a) Would everyone come down with the illness? Why or why not?

b) If not, how would you explain the variability in response in terms of 1) differences attributable to pathogens and 2) differences attributable to humans?

A. In a Meselson-Stahl type experiment, bacterial cells grown in 15N medium for many generations were washed and then allowed to grow in 14N medium. DNA was extracted just after transfer (0 generation) and then after 1 and 2 generations. All these samples were analyzed by CsCl gradient centrifugation. From DNA isolated from generations 0, 1 and 2 show.
