A reseаrcher intrоduces аn аntibiоtic resistance gene intо a population of E. coli. Over time, some cells that were initially sensitive acquire resistance. Upon investigation, it is found that: Some cells took up DNA from dead cells in the environment. Some cells received DNA through bacteriophages. Some cells received a plasmid directly from neighboring cells via a pilus. Which terms correctly describe these three gene transfer events?
