State whether the following statements are true or false.
Transduction is a phage-mediated genetic transfer.
A. True
B. False

Answer

To determine whether the statement "Transduction is a phage-mediated genetic transfer" is true or false, we can follow these steps:

### Step-by-Step Solution:

1. **Understand Transduction**: Transduction is a process in microbiology where genetic material is transferred from one bacterium to another by a virus that infects bacteria, known as a bacteriophage.

2. **Identify the Role of Bacteriophage**: In transduction, the bacteriophage acts as a vector that carries genetic material from a donor bacterium to a recipient bacterium. This process can occur during the bacteriophage's life cycle.

3. **Confirm the Mechanism**: During transduction, the bacteriophage infects a bacterium, incorporates some of the bacterium's DNA, and then transfers this DNA to another bacterium when it infects it. This confirms that the transfer of genetic material is mediated by the phage.

4. **Evaluate the Statement**: The statement claims that transduction is a phage-mediated genetic transfer. Since we have established that transduction involves the use of bacteriophages to transfer genetic material, the statement is indeed correct.

5. **Choose the Answer**: Based on the above reasoning, we conclude that the statement is true.

### Final Answer:
A. True
