The transfer of genes during bacterial conjugation involves the pili.
Pili
Bacterial pili (singular: pilus) are special outgrowths on the surface of some bacterial cells that act as conjugal tubes during the process of transferring genes from one cell, the donor, to another, the recipient.
The pili extend from the donor to the recipient and then form channels through which genes are transferred.
