You are studying several alleles of an E. coli helicase gene. One alles, called rs^R, conifers resistance to RS2014, an anitbiotic that works by inhibiting helicase activity. Bacteria with the rs^s 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 degrees C, …
