FIGURE 3: Methylation protection footprint on BrdU-substituted DNAs. In each DNA, BrdU was substituted by automated DNA synthesis for one nucleotide in 02T. Position 1 is the 3' G. (A) Irradiation of BrdU-substituted nucleoprotein complexes, followed by SDS-PAGE/autoradiography. Open arrowhead: cross-link to the subunit. Filled arrowheads: cross-links to a. (B) BrdUsubstituted nucleoprotein complexes analyzed by methylation protection as described (Fang et al., 1993). Not shown is the methylation of protein-free DNA, which produces a uniform ladder of cleavage at Gs; cf. Gray et al. (1991).

by PCR amplificationof genomicclonesusing primersnear the intron/ exon boundaries. The amplified product sizes were determined by mobility in agarose gel electrophoresis as compared to standards shown on the left. Lune a, intron 1 (I 1) amplified from clone G-1.3; lune b, intron 2 (12) amplified from clone G-2.2; lune c, intron 3 (13) amplified from clone G-2.2. Calculated sizes for the PCR products were the following: intron 1, 3300 bp; intron 2, 2900 bp; intron 3, 630 bp. Subtraction of the distance between primers in the cDNA yielded net sizes for the introns as follows: intron 1,2900 bp; intron 2, 2700 bp; intron 3,400 bp.
