Bacterial conjugation. Animation showing genetic material being transferred from one bacterium to another. A DNA plasmid (circle of deoxyribonucleic acid, pale blue) is passed from the donor bacterium (F+) to the recipient bacterium (F-) through an enlarged pilus (hair-like structure, centre) that acts as a bridge. Once transferred, the plasmid is incorporated into the recipient bacterium's DNA. This mechanism helps bacteria spread beneficial traits such as drug resistance. | |
