Question

which best describes transduction in bacteria? A:Bacteria transfer DNA with bacteriophages B:Bacteria inject DNA into other cells C: Bacteria change from lysogenic to lytic D:Bacteria take in DNA from their environment

Answer 1

Answer:

Option A : Bacteria transfer DNA with bacteriophages

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.

Answer 2

Bacteria transferring DNA with a bacteriophage and bacteria taking DNA from their environment both best describe transduction in bacteria.
