Donor strain of bacteria with His+ Ara+ Met+ Leu+ Cys+ Lys+ is infected with phages to map the donor chromosome with generalized transduction .The Phage lysate from bacterial cell is collected and use to infect second strain of bacteria that are His- Ara- Met- Leu- Cys- Lys- . Different transducing phages are selected on using different minimal media and their presence of growth (+) and absence of growth (-) given in table
