Here's a breakdown:
* Pilus (plural: pili): These are hair-like appendages on the surface of some bacteria.
* Conjugation: This is a process where one bacterium (the donor) transfers genetic material to another bacterium (the recipient) through direct contact.
* Process:
* The donor bacterium forms a pilus that attaches to the recipient bacterium.
* The pilus acts as a bridge, allowing a copy of the donor's DNA (often a plasmid) to be transferred to the recipient.
* The recipient bacterium can then incorporate this new DNA into its own genome.
This exchange of genetic material through conjugation allows bacteria to share advantageous traits, such as antibiotic resistance, with each other.
