Alu elements are a type of transposable element. They possess the means for their own duplication and movement. Alu is a SINE-like element that is transcribed by RNA Pol III, and so a single DNA copy can make multiple RNA copies, each capable of inserting into DNA, so it's no wonder they have a very high copy number.y 2008 biology book (1) states that some 10% of the human genome consists of relatively short (~300 nucleotides long) Alu elements which do not code for proteins but many of which are transcribed into RNA.
