Understand the concept of bacterial conjugation: Conjugation is a process where genetic material is transferred between bacterial cells through direct contact.
Identify the key components involved in conjugation: The donor bacterium must possess a plasmid, which is a small, circular piece of DNA that can replicate independently of chromosomal DNA.
Recognize the role of the plasmid: The plasmid contains genes that encode the formation of a pilus, a hair-like appendage that facilitates the connection between bacterial cells.
Clarify the function of the pilus: The pilus acts as a bridge, allowing the transfer of genetic material from the donor to the recipient bacterium.
Conclude the correct pairing: For a bacterium to conjugate, it must possess a plasmid with genes that encode a pilus.
