Nonpathogenic Vibrio cholerae can acquire the cholera toxin gene by which of the following processes?
A
Conjugation
B
Binary fission
C
Transformation
D
Transduction
Verified step by step guidance1
Understand the different mechanisms by which bacteria can acquire new genetic material: conjugation, transformation, and transduction.
Recall that conjugation involves direct transfer of DNA between bacterial cells through a pilus, typically plasmid DNA.
Recognize that binary fission is a method of asexual reproduction in bacteria and does not involve acquiring new genes from other organisms.
Know that transduction involves transfer of bacterial DNA via bacteriophages (viruses that infect bacteria).
Identify transformation as the process where bacteria take up free DNA fragments from their environment, which is how nonpathogenic Vibrio cholerae can acquire the cholera toxin gene.
