Disease Control (CDC) determine that the agent causing the birds to die is the West Nile virus. Outbreaks of this illness have been observed in several other countries in Asia and the Middle East across the last 50 years, but not in the United States. With this information, what would be the best categorization of this infectious agent/disease

#SCPH06 I Botany

  1. This is clearly a reemerging infection. It's been around for a long time, and it is reappearing in a susceptible population again.

  2. This is clearly a nosocomial infection. It's transmitted from animals to human beings in urban environments.

  3. This is clearly an emerging infection. It hasn't been around that long, and it has made a jump across continents into a new susceptible population.

  4. This is clearly not a concern to human beings--maybe it's emerging in animals, maybe it's reemerging, maybe it's nosomial. But who cares? It's only in birds.

#SCPH06 I Botany

5 You are studying regulation of the yeast enzyme glutamine synthetase (GS), which is encoded by the GLN1 gene. You have isolated two mutants, designated gln2– and gln3–, that give decreased GS activity. Mating of either gln2– or gln3– haploids to wild type produces heterozygous diploids that show normal amounts of GS expression. When you cross either a gln2– or gln3– haploid to a gln1– strain the resulting diploids show normal expression of GS.
Describe the cis-acting elements in the GLN1 promoter that are evident from these experiments, giving both their position and as much of their function as you can deduce.
