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.
Annotation: GEN: prefer specifics - DNA TRANSPOSABLE ELEMENTS or RETROELEMENTS or its indentions
Allowable Qualifiers: DE drug effects
ES ethics
GE genetics
IM immunology
PH physiology
RE radiation effects
History Note: 99; for MOBILE GENETIC ELEMENTS use DNA TRANSPOSABLE ELEMENTS 1986-98; for SELFISH DNA use DNA (1983-2003)
