Definition
English
:
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.
