mobile genetic element

mobile genetic element

(1) A DNA sequence (e.g., insertion sequence or transposon) that promotes its own transposition.
(2) A DNA sequence on a chromosomes that can move to new sites in the genome other than by mutation.

mobile genetic element

broadly any genetic element capable of moving itself, with or without duplication, from one site in a genome to another, or from one cell to another. Mobile genetic elements include PLASMIDS, VIRUSES, TRANSPOSABLE GENETIC ELEMENTS, short interspersed elements (SINES), PATHOGENICITY ISLANDS and so on. However, the term is often restricted to transposable genetic elements.
