Microbial Recombination and Gene Transfer
The main difference between a self-transmissible and a mobilizable plasmid is that the self-transmissible plasmid

transfers both strands of the plasmid DNA
carries genes encoding the mating apparatus
usually has a transposon inserted into it
transfers antibiotic resistance genes
