Which of the following processes results in a transducing particle?

• A. Transformation.
• B. Transduction
• C. Conjugation.
• D. DNA replication.

Answer: (B)

Verified step by step guidance

1. Understand the concept of transduction: Transduction is a process where bacterial DNA is transferred from one bacterium to another by a virus, specifically a bacteriophage.
2. Identify the role of bacteriophages: In transduction, bacteriophages infect bacterial cells and can accidentally package bacterial DNA into new viral particles, creating transducing particles.
3. Differentiate transduction from other processes: Transformation involves uptake of naked DNA from the environment, conjugation involves direct transfer of DNA between bacteria through a pilus, and DNA replication is the process of copying DNA within a cell.
4. Recognize the formation of transducing particles: During the lytic cycle of a bacteriophage, bacterial DNA can be mistakenly packaged into a phage particle instead of viral DNA, resulting in a transducing particle.
5. Conclude that transduction is the process that results in transducing particles, as it involves the transfer of bacterial DNA via bacteriophages.
