Transposable Elements - Transposable elements are segments of DNA which can insert into several sites in a genome. They have been found inserted in the genomes of both prokaryote and eukaryote cells. They can move from one position to other nonhomologous regions. Transposable elements influence the activity of genes near the sites of insertion and can also cause chromosomal aberrations. The three classes of transposable elements are IS elements, Tn elements (transposons) and episomes.
