A, representative screen shots are shown for rDNA (M. musculus 45S pre-rRNA gene, X82564.1) in the top panel and Dhfr in the bottom panel. B, quantitative analysis of two experiments are plotted in the bar graph. NS, not significant; *, p < 0.05, Student's t test. C, frequency of the relevant dinucleotide, T-T, at each position of the 26-nt XR-seq excision fragments mapped to rDNA (X82564.1) and Dhfr, respectively.
