Bacterial gene transfer is also used in the lab to introduce genes into organisms of different species, genera, phyla, or even kingdoms or domains. a major example is the use of a ti plasmid of the soil bacterium agrobacterium tumefaciens to transfer genes into dicotyledonous plants. the bacterium infects the plant root in the soil and transfers some of the ti plasmid genes (t dna) into the plant nucleus. recombination may occur, and t dna expression is controlled by plant compounds generated in response to wounding and infection. the t dna is generated when there is a nick that creates a primer for replication, followed by transfer of a single-stranded dna piece that converts to a double-stranded piece in the plant nucleus. which of these processes is ti plasmid transfer most like? specialized transduction transformation conjugation generalized transduction.

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.
