Answer:
C. Luria Agar + kanamycin + tetracycline
Explanation:
Given that the recipient strain is tetracycline resistance and the donor strain is tetracycline sensitive.
Recipient strain is kanamycin sensitive and the donor strain is kanamycin resistance sensitive.
If we grow the recipient cell in Luria agar containing tetracycline then only recipient cells will grow and all the donor cells will die.
If we grow the recipient cell in Luria agar containing kanamycin then only recipient cells that have undergone transposon mutagenesis will grow and along with donor cells.
If the Luria agar has both kanamycin and tetracycline then only the recipient cells that have undergone transposon mutagenesis will grow.
Since recipient cells will acquire pir gene. So it will not require pir in the media.
So correct answer is option C. Luria Agar + kanamycin + tetracycline
