In a hypothetical situation, the gene for tetracycline resistance is located on a plasmid within a particular bacterium. This bacterium readily forms a pilus and donates one strand of the plasmid to another bacterium. What do you know about the bacterium with the tetracycline resistance? O It cannot receive a plasmid from another bacterium. O It must have the F factor gene because it can perform conjugation. O If it donates the plasmid, it will lose its own tetracycline resistance. O It has the Hfr gene and it can participate in transformation.
