Guida verificata passo dopo passo1
Understand that bacterial conjugation is a process where genetic material is transferred from one bacterial cell to another.
Recognize that the pilus, specifically the sex pilus or conjugative pilus, is a structure involved in this process.
Recall that the pilus forms a physical connection between two bacterial cells, allowing the transfer of DNA, usually plasmids.
Note that the pilus does not function in motility like a flagellum, nor does it act as a protective barrier or enable photosynthesis.
Conclude that the primary role of the pilus during bacterial conjugation is to facilitate the transfer of genetic material between bacterial cells.
