Gonorrhea is a sexually transmissible disease (STD) caused by the bacterium Neiserria gonorrhoeae. In the 1940s, penicillin was introduced as an antibiotic to treat gonorrhea. In particular, the drug inhibits the formation of new cell walls in dividing bacterial cells, making new cells vulnerable to the human body's defences. However, a new strain of Neiserria gonorrhoeae was found that is capable of breaking down penicillin, making this strain resistant. The emergence of this new strain has been associated with instances of non-strict compliance of certain patients on the use of penicillin as well as the improper administration of the drug. Based on the information given, formulate a strategy that could help control this new strain.

This question combines your knowledge of bacterial conjugationand the genetic regulation that directs thephage λ reproductive cycles. When researchers mix donor Hfr strains with recipient F– bacteria that are lysogenic for phage λ, the conjugated cells survive normally. However, if donor Hfr strains that are lysogenic for phage λ conjugate with recipient F– bacteria that do not contain any phage λ, the recipient cells often lyse, due to the induction of λ into the lytic cycle. Based on your knowledge of the regulation of the two reproductive cycles of phage λ, explain this experimental observation.

The figure below shows the life cycle of the fungus Neurospora. The adult stage of the Neurospora is a multicellular haploid. b) Neurospora has an arginine amino acid synthesis pathway shown below. Suppose I take the strain above that only grows with arginine supplements and cross it to a different mutant Neurospora strain that grows with arginine and citrulline supplements but not with ornithine supplements. Assuming gens A, B, and C are unlinked and there is only one mutation per stain: What percentage of the progeny will grow on ornithine? What percentage on citrulline? What percentage on arginine?
