Transformation and Transduction • Conjugative Transposons • These genetic elements share attributes with conjugal plasmids and transposons • A transposition event between two cells • Requires all the functions found in conjugation plus those of transposition. The process results in a stable genetic change within the transformed cell. The actual transfer of genetic material between bacteria usually takes place in one of three ways: direct transfer between two bacteria temporarily in physical contact (conjugation), transfer of a naked DNA fragment (transformation), or transport of bacterial DNA by bacteriophages (transduction).
