Question:
Which one of the following statements is INCORRECT with respect to bacterial conjugation?
Which one of the following statements is INCORRECT with respect to bacterial conjugation?
Show Hint
Bacterial conjugation involves the transfer of genetic material via a sex pilus, not a flagellum. It plays a role in the spread of antibiotic resistance and virulence factors.
Updated On: Dec 11, 2025
- It facilitates transfer of genetic material
- It requires flagellum
- It can spread antibiotic resistance
- It can transfer virulence factors
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding bacterial conjugation.
Bacterial conjugation is a process by which genetic material is transferred from one bacterium to another through direct contact. This process does not require a flagellum; instead, a sex pilus is used to connect the two bacteria.
Step 2: Analyzing the options.
(A) It facilitates transfer of genetic material: Correct — Conjugation is the process of transferring genetic material between bacteria.
(B) It requires flagellum: Incorrect — Conjugation requires a sex pilus, not a flagellum.
(C) It can spread antibiotic resistance: Correct — Conjugation is a major mechanism for the spread of antibiotic resistance.
(D) It can transfer virulence factors: Correct — Conjugation can also transfer genes related to virulence.
Step 3: Conclusion.
The correct answer is (B) It requires flagellum, as conjugation actually requires a sex pilus, not a flagellum.
