A 20-year-old male has presented to a health clinic with multiple genital lesions that are filled with a viscous, creamy exudate and has subsequently been diagnosed with molluscum contagiosum. What is his care provider most likely to tell him about the plan for treating the diagnosis?
a) "This kind of infection often subsides on its own and doesn't grow more serious over time."
b) "These lesions usually respond well to oral antiviral medications."
c) "Treatment of this problem is usually successful, but if untreated, it can lead to sterility."
d) "The bacteria that cause this disease are often latent for several years at a time, and you would be contagious for the entire period."

You are studying several alleles of an e. coli helicase gene. one allele, called rsr, confers resistance to rs2014, an antibiotic that works by inhibiting helicase activity. bacteria with the rss allele are sensitive to rs2014. another allele, called ts-, produces a temperature sensitive mutation of the helicase. in bacteria with the ts- allele, helicase is inactivated at 42 °c but functions normally at 37 °c. helicase functions normally at both temperatures in bacteria with the ts allele. you obtain the following data while testing four strains of e. coli at different temperatures and doses of rs2014. each number represents the percentage of maximal dna synthesis. based on this data, assign the appropriate genotype to strains a–d in the spaces provided
