[{'content': 'A bacterium acquires an antibiotic-resistance gene that is carried by a phage vector. The phage vector does not carry randomly chosen poions of bacterial DNA, but instead almost always carries primarily the antibiotic-resistance gene. This is an example of which of the following? \nSelect and explain. \nA. Conjugation, B. Generalized transduction, C. Site-specific transduction, D. Transformation', 'role': 'user'}, {'content': "Answer: C \nExplanation: Transduction is the term used for DNA transfer a bacteriophage vector. Transduction that involves specific genomic information is called site-specific transduction. Conjugation is direct DNA transfer between bacteria sex pili. Generalized transduction is a non selective DNA transfer a bacteriophage vector. Transformation is the uptake of naked DNA from the environment. Ref: Brooks G.F. (2013). Chapter 7.
