Higher magnification of the (A) 5' flanking (upstream of exon 1), and (B) 3' flanking region of Myc. The handle bars in green represent the retroviral insertions; arrows in the line within the bars denote direction of provirus transcription. Proviruses boxed in red are in the same orientation as the Myc gene (from left to right), opposite from the rest. Proviruses are in the same orientation as the Myc gene.
