MeSH Heading: Interspersed Repetitive Sequences
Tree Number(s): G02.111.570.080.708.330; G05.360.080.708.330; G05.360.340.024.425
Unique ID: D020071
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D020071
Annotation: general or unspecified; prefer specifics
Scope Note: 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.
