Correctly match the mechanisms of bacterial genetic exchange with the correct description (multiple answers possible): transfer of free or “naked” DNA from environment                                                 Conjugation   transfer via bacteriophage                                                                                   Transduction transfer require direct contact b/w cells                                                     Transformation transfer requires competent recipient cell transfer mediated by fertility plasmid transfer allows only uptake of DNA by related species in nature transfer can be both chromosomal and plasmid DNA
