bacterial strain the transducing partical infects

cells that have received DNA from another bacterium by transduction

• phage DNA either is integrated into the host chromosome
• or replicates as a plasmid

• lysogen-forming phage
• be able to maintain a stable relationship with the host cell
• inwhich they neither multiply nor are lost from the cell

phage DNA in the lysogenic state is called a ~

the bacterium harboring a prophage is a ~ for that phage
