In conjugation, DNA is transferred from one bacterium to another. After the donor cell pulls itself close to the recipient using a structure called a pilus, DNA is transferred between cells. In most cases, this DNA is in the form of a plasmid.

What causes conjugation to occur?

The transfer of genetic information between two bacterial cells may occur via cell-to-cell contact. ... The donor cell manufactures a sex pilus that binds to the recipient and draws the two cells together. Next, a conjugation bridge forms between the two cells and provides a channel for DNA to move from donor to recipient.

Where does conjugation take place?

Bacterial conjugation is the transfer of genetic material between bacterial cells by direct cell-to-cell contact or by a bridge-like connection between two cells. This takes place through a pilus. It is a parasexual mode of reproduction in bacteria.
