Fig. 7.

Pie charts showing number of insertions or deletions between human and macaque promoters. a Number of detected indel sites is classified by length. More than half were single-nucleotide insertions or deletions. The longest indel detected was 35 bp. b–d Types of nucleotides detected in alignments are shown between CpG-island promoters (b), CpG-island and non-CpG-island promoters (c), and non-CpG-island promoters (d). In CpG-island promoters, inserted or deleted nucleotides were biased toward C or G. hCmC CpG-island promoter in human and macaque, hNmC CpG-island promoter in macaque and not in human, hCmN CpG-island promoter in human and not in macaque, and hNmN non-CpG-island promoters in the two species
