Conjugation is the process in bacteria where DNA is transferred from one bacterium to another through a structure called a pilus (a type - of hollow bridge). Transformation involves the uptake of free - floating DNA from the environment by a bacterium, and transduction is the transfer of DNA by bacteriophages (viruses that infect bacteria).
