Alu element

An Alu element is a short stretch of DNA originally characterized by the action of the Alu (Arthrobacter luteus) restriction endonuclease. Alu elements of different kinds occur in large numbers in primate genomes. In fact, Alu elements are the most abundant transposable elements in the human genome. They are derived from the small cytoplasmic 7SL RNA, a component of the signal recognition particle. The event, when a copy of the 7SL RNA became a precursor of the Alu elements, took place in the genome of an ancestor of Supraprimates.
