Answer:
Option A : Bacteria transfer DNA with bacteriophages
Step-by-step explanation:
The transduction is the process by which foreign DNA is inserted into the cell. The DNA is inserted by viral vector or virus. This process was discovered by Zinder and Lederberg. Bacteria transfer DNA with bacteriophages is called transduction. The bacteriophage is a virus that replicates within the bacterial cell. Thus, Option A is correct.
Bacteria inject DNA into other cells with the help of a tube , this process is called Conjugation. Bacteria change from lysogenic to lytic is called induction. Bacteria take in DNA from their environment is called transformation. Thus, Option B, C, D are incorrect.
