Distribution of bisulfite Alu clones with different methylated-CpG number and variations at CpG sites. The accumulated proportion of bisulfite clones with different number of methylated-CpGs (A, left), and the constituent ratio of various dinucleotides at the 17 CpG sites of Alu clones (A, right). The distribution of the number of CpG, TpG, TpA, and other variations among Alu clones from bisulfite-treated templates with a different number of methylated-CpGs was illustrated (B).
