What is competence
How well bacteria take up naked DNA from the environment (transformation)
Define Hfr
High-frequency recombination cell
When F+ plasmid is incorporated into bacterial chromosome
Define transduction
Transfer of DNA from one bacteria to another using virus
Does not require contact (like conjugation)
Is either lytic or lysogenic
