Figure 4.

Restriction maps of Alu repeats. Most conserved recognition sites of restriction enzymes are shown at top. Electrophoregrams of human genomic DNA enzymatic cleavage (8% PAAG) and lengths of fragments are shown at left. A correspondence of predicted DNA fragments (arrows) to the bands in electrophoregrams is shown by dotted lines. M – DNA ladder pUC19/MspI (the lengths of visible fragments are: 501, 489, 404, 331, 242, 190, 147, 111+110, 67 and 34 bp, from top to bottom). "sat" – α-satellite DNA cleavage products.
