Interspersed repetitive sequences

Interspersed repetitive sequences Copies of transposable elements interspersed throughout the genome, some of which are still active and often referred to as "jumping genes". There are two classes of interspersed repetitive elements. Class I elements (or retroelements - such as retrotransposons, retroviruses, long interspersed nucleotide elements and short interspersed nucleotide elements) transpose via reverse transcription of an RNA intermediate. Class II elements (or DNA transposable elements - such as transposons, Tn elements, insertion sequence elements and mobile gene cassettes of bacterial integrons) transpose directly from one site in the DNA to another.
