Figure 2.

Representation of MuDR at p1 and Mu1 at a1-mum2. Shaded boxes represent Mutator TIRs; open boxes are Mutator internal sequences that differ between MuDR and Mu1. The mudrA and mudrB exons are solid boxes just below the MuDR element; the lines that angle down represent introns. Arrows indicate the direction of transcription. Restriction sites used in this study are indicated. Probes used in this study are indicated below the transcripts. Primers used in this study are shown as arrowheads.
