Figure 3. The enhancer-blocking activity of the Fab-7 insulator in one copy.

Figure 3

Transgenic lines were grouped into those in which the Fab-7 insulator (F7, black rectangle) displayed (A) weak or (B) strong enhancer-blocking activity. (C) Homozygous transgenic lines in which the Fab-7 insulator displayed a weak enhancer-blocking activity. Other designations are as in Figure 1.
