Alu Element Definition:

  • A human nonautonomous retrotransposon that contains the AGCT sequence recognized by the restriction enzyme AluI. Present in about 1 million copies in the human genome..

    Molecular Biology by Robert F. Weaver



Alu Element Explanation:

An Alu Element is a short fragment of the DNA (containing the AGCT sequence), which is originally characterized by the action of the enzyme, Alu (Arthrobacter luteus) restriction endonuclease. These are the most abundant transposable elements, dispersed throughout the human genome (present in over one million copies).
