Which method of DNA exchange does NOT require a virus?
Understand the Problem
The question is asking about the methods of DNA exchange in microorganisms and specifically which of those methods does not involve a virus. It provides multiple-choice answers related to microbial genetics.
Answer
Transformation does not require a virus.
The method of DNA exchange that does not require a virus is transformation, where bacteria uptake extracellular DNA.
Answer for screen readers
The method of DNA exchange that does not require a virus is transformation, where bacteria uptake extracellular DNA.
More Information
In transformation, bacteria can directly take up free DNA fragments from their surroundings and integrate them into their own genomes, allowing genetic variation without the need for viral intermediaries.
Tips
Confusing transformation with transduction, which involves viruses, is a common mistake.
