composite transposon

A transposon constructed of two IS (insertion sequence) elements flanking a control region that frequently contains host genes….

transposable genetic element

A general term for any genetic unit that can insert into a chromosome, exit, and relocate; includes insertion sequences, transposons, some bacteriophages, and controlling element. A region of the genome, flanked by inverted repeats, a copy of which can be inserted at another place; also called a transposon or a jumping gene….

inverted repeat (IR) sequence

A sequence found in identical (but inverted) form, for example, at the opposite ends of a transposon. A nucleotide sequence found at two sites on the same double helix but in opposite orientation….

enhancer trap

A transgenic construction inserted in a chromosome which is used to identify tissue-specific enhancers in the genome. In such a construct, a promoter sensitive to enhancer regulation is fused to a reporter gene, such that expression patterns of the reporter gene identify the spatial regulation conferred by nearby enhancers. “In contrast to the rational “one gene at a time” approaches, enhancer-trapping methods evolved to probe…

retrotransposon

A class of genetic elements that includes retroviruses and transposons that have an intermediate RNA stage. A transposon that was created by reverse transcription of an RNA molecule….
