1.Your research group is investigating the possible use of
genetically-engineered cells to produce a vaccine for malaria. List
the pros and cons of using E. coli, Saccharomyces, and animal cells to
produce the vaccine.
2.The local public health agency has received reports of an outbreak of
Salmonella gastroenteritis among attendees at a city-sponsored chili
cook-off. What techniques from recombinant DNA technology would the
agency likely use to investigate this outbreak? Describe the expected
results from these techniques.
3. Pseudomonas syringae is found naturally in the soil. Sold as Snomax,
it is used to make snow at ski resorts. The same bacterium with a gene
deletion (Ice-minus) is used to prevent ice formation on plants.
Should Snomax and Ice-minus be considered modified organisms and
subject to precautions of releasing genetically modified organisms?
Explain why or why not.
