Transposons are genes that can move. They have a specific target site,allowing them to move or 'jump' into different DNA sites[1]. Transposons leave copies of themselves wherever they stop. Half of the human genome consists of these 'jumping genes'[2]. They are important for genomic variation and evolution in organisms. Transposons are subdivided into 2 classes:
