Abstract
Transposable elements are DNA sequences that are able to move from place to place in the genome, and in some cases, make copies of themselves and reinsert back into the genome. Transposable elements are divided into three classes based on their method of transposition. Class I elements transpose by an RNA intermediate, and these include L TR (long terminal repeat) and non-L TR retrotransposons. Class II elements relocate in the genome without duplication. Interestingly, class III elements entirely lack genes and rely on products of other elements for transposition. Transposable elements are no longer considered unusual or unique components of genomes. Instead, DNA sequencing has revealed that at least one type of .transposable element can be found in all organisms [2]. The situation in plants is even more remarkable, as in some species with large and complex genomes where transposable elements can account for greater than 50% of nuclear DNA.
