COMMON COLD
a. Name two of the most common viruses to cause a cold.
b. What is the most common route of transmission?
c. Why do more colds happen in the winter?
d. Does taking large doses of vitamin C or Echinacea help with
prevention or symptoms of the common cold?
VIRAL GASTRITIS
Name two of the most common viruses to cause the stomach
flu.
b. What is the most common route of transmission?
c. What are the symptoms? What is the treatment?
d. How does the stomach flu caused by a virus differ from one
caused by bacteria?
PNEUMONIA
a. Name two of the most common viruses to cause viral
pneumonia.
b. How does pneumonia differ from the common cold?
c. How does pneumonia caused by a virus differ from one caused
by bacteria?
Drugs against viruses are usually designed to affect viral
genome replication.
i) Describe the various mechanisms by which viral genomes
replicate and also synthesize protein. Your answer needs to focus
only on genome replication and protein synthesis; do not include
the other replication steps.
The haplodiplontic life cycle is common in plants and
algae (but absent in animals). Briefly describe the life cycle of a
flowering plant, including the name and ploidy of each stage, and
the relevant structures involved in transitioning from one stage to
the next.
Given the viral life cycle pictured, identify 3 stages of the
cycle which you might target with a therapeutic molecule in order
to both (i) prevent or inhibit spread of the virus, and (ii) avoid
affecting human cells. Explain your choice in detail in all
cases.
