Transposable elements are mediators for bacterial gene transfer and are active during recombinant processes such as conjugation[1]. The most basic transposable element is the insertion sequence which is 1-3 kb long and has the genes encoding a key transposase protein[2]. The insertion sequence has inverted repeat sequences on either side which activate it[3]

Other genes which are unable to ransfer on their own may associate themselves within insertion sequences forming  transposons[4]. Genes encoding antibiotic resistance are spread rapidly through bacterial populations via this method of association[5]
