Use this information to answer the question(s) below. suppose an experimenter becomes proficient with a technique that allows her to move dna sequences within a prokaryotic genome. if she moves the promoter for the lac operon to the region between the beta galactosidase (lacz) gene and the permease (lacy) gene, which of the following would be likely? the three structural genes will be expressed normally. rna polymerase will no longer transcribe permease. beta galactosidase will not be produced. the operon will still transcribe the lacz and lacy genes, but the mrna will not be translated.

In 1959, doctors began using the powerful antibiotic methicillin to treat infections of staphylococcus aureus, but within two years, methicillin-resistant strains of s. aureus (mrsa) appeared. how did the resistant strains of s. aureus emerge? in 1959, doctors began using the powerful antibiotic methicillin to treat infections of staphylococcus aureus, but within two years, methicillin-resistant strains of s. aureus (mrsa) appeared. how did the resistant strains of s. aureus emerge? staphylococcus aureus bacteria that were able to synthesize cell walls using a protein that was not affected by methicillin survived the methicillin treatments and reproduced at higher rates than did other individuals. over time, these resistant individuals became increasingly common. in response to treatment of staphylococcus aureus infections with methicillin, some bacteria began to synthesize cell walls using a protein that was not affected by methicillin. these bacteria survived the methicillin treatments and reproduced at higher rates than did other individuals. over time, these resistant individuals became increasingly common. in response to treatment of staphylococcus aureus infections with methicillin, bacterial populations gradually began to synthesize cell walls using a protein that was not affected by methicillin.
