Many transposable elements appear to be genomic parasites, existing in large numbers because of their ability to efficiently increase in copy number. Increases in copy number of transposable elements have contributed to the large size of may eukaryotic genomes. In several cases, transposable elements and their ability to transpose have been adopted for specific cellular functions.
