Figure 1From: The expanding universe of transposon technologies for gene and cell engineeringGeneral organization and use of class II transposable elements as gene vectors. (A) Autonomous transposable elements consist of terminal inverted repeats (TIR; black arrows) that flank the transposase gene. (B) Bi-component transposon vector system for delivering transgenes that are maintained in plasmids. One component contains a DNA of interest between the transposon TIRs carried by a plasmid vector, whereas the other component is a transposase expression plasmid, in which the black arrow represents the promoter driving expression of the transposase. (C) The transposon carrying a DNA of interest is excised from the donor plasmid and is integrated at a chromosomal site by the transposase.Back to article page
