Function of pilus in bacteria is to:
Correct answer: D. Exchange of genetic material
- A. Increase pathogenicity of bacteria
- B. Degrade host plasma membrane
- C. Degrade host enzymes
- D. Exchange of genetic material
Explanation
Pili (singular: pilus) arehair-like appendages found on the surface of some bacterial cells. One of the primary functions of pili is to facilitate the exchange of genetic material between bacterial cells, a process known as bacterial conjugation.Role of pili in bacterial conjugation- Pili act as a bridge between two bacterial cells, allowing for direct cell-to-cell contact.- The pilus of one bacterium attaches to a receptor on the surface of another bacterium.- The attached bacteria then form a conjugation bridge, allowing for the transfer of genetic material, such as plasmids.
