Transposable elements- definition, types, examples, applications


Transposable elements (TEs) or transposons are segments of DNA that can move from one location to another within the genome of a cell or an organism. They are also called "jumping genes" because they can jump across chromosomes or plasmids, sometimes creating mutations or rearrangements in the process. TEs are found in almost all living organisms, from bacteria to humans, and they constitute a large proportion of the genetic material in many species.
