Transposable genetic elements are discrete DNA segments with the capacity to move between independent DNA replicons within the cell. The recent discoveries that certain plasmid-borne genes, which confer resistance to antibiotics and to heavy metals, are components of transposable elements has improved our understanding of how plasmids might pick up genes from nonhomologous DNA molecules during their evolution and during the spread of antibiotic resistant infections in hospitals. Table 1 illustrates that many determinants of resistance have already been found in transposable elements. Considerable diversity is seen in this collection of elements: they vary in their DNA sequence arrangement, in the frequency and specificity of transposition, and in the stability of the transposed genes. Some contain known insertion sequences.
