An Alu element is a short stretch of DNA originally characterized by the action of the Arthrobacter luteus (Alu) restriction endonuclease. Alu elements are the most abundant transposable elements in the human genome, present in excess of one million copies. Most Alu elements are thought to be selfish or parasitic DNA. However, it has been suggested that at least some are likely to play a role in evolution and have been used as genetic markers. They are derived from the small cytoplasmic 7SL RNA, a component of the signal recognition particle. Alu elements are not highly conserved within primate genomes, as only a minority have retained activity, and originated in the genome of an ancestor of Supraprimates.
