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.

The fourth region (R4, 14 ORFs from ORF20 to ORF40) mainly contains a mobile genetic element. It includes a fragment (named R4') inserted into the umuC gene, which is characterized by a phage integrase (ORF38) and a phage integrase family site-specific recombinase (ORF37) and encodes 9 genes from different origins with various functions.
