Question

multiple choice question

which form of genetic recombination involves dna transfer that is mediated through the action of bacterial viruses?

conjugation
transformation
transduction

Explanation:

Identify the mechanism of viral-mediated DNA transfer

The question asks for the form of genetic recombination in bacteria that is mediated by bacterial viruses (bacteriophages).

Evaluate the given options

• Conjugation: Transfer of DNA directly from one bacterium to another via physical contact (sex pilus).
• Transformation: Uptake of naked, foreign DNA from the surrounding environment.
• Transduction: Transfer of bacterial DNA from a donor cell to a recipient cell mediated by a bacteriophage (bacterial virus).

Answer:

• Conjugation
• Transformation
• Transduction (Correct answer)
