Contains a tandem repeat of the w+ and rst+ genes bounded by FB elements. There are also NOF sequences within the TE. Both copies of rst appear to have a NEB element inserted at a similar site. The copies of w probably carry a small (approximately 250bp) insertion, which is probably a copia LTR. The junctions between FB and non-FB sequences within Tp(1;2)TE35B have been molecularly mapped.
