Using an Alu Insertion Polymorphism to Study Human
... Alu is a member of the family of short interspersed elements (SINEs) and is approximately 300 nucleotides in length. Alu owes its name to a recognition site for the endonuclease AluI in its middle. Although Alu is sometimes called a “jumping gene,” it is not properly a gene, because it does not prod ...

Mutagen
In genetics, a mutagen is a physical or chemical agent that changes the genetic material, usually DNA, of an organism and thus increases the frequency of mutations above the natural background level. As many mutations can cause cancer, mutagens are therefore also likely to be carcinogens. Not all mutations are caused by mutagens: so-called ""spontaneous mutations"" occur due to spontaneous hydrolysis, errors in DNA replication, repair and recombination.
