Abstract
In recent years, transposable genetic elements have been shown to be important both in the structural evolution of prokaryotic genomes and in the control of gene expression within bacterial cells (for reviews, see Cohen 1976; Starlinger and Saedler 1976; Kleckner 1977). A variety of structurally distinct segments of DNA are capable of transposition (translocation) as intact units between DNA molecules that apparently have little or no homology with each other or with the transposable element. Since each transposable element consists of a structurally defined segment of DNA, its movement between separate genomes as an intact unit implies the existence of a mechanism for recognition of the element's terminal nucleotide sequences. In at least some instances, translocation also requires expression of genetic information carried by the element itself (HefTron et al. 1977).
