Figure I. Schematics of the transposition mechanisms for the three major groups of TEs, with special reference to points in the process where the possibility of HTT is especially high.

Figure I

White circles with solid borders are cells, gray circles with dashed borders are nuclei; bold lines indicate host DNA (black = donor site, grey = recipient site); TEs are represented by red boxes (DNA) or squiggly lines (mRNA); protein products are represented by shaded circles and ovals; thick black arrows indicate stage in transposition during which TEs are disassociated from host genomic DNA and thought to be most likely to horizontally transfer.
