Fig. 3From: Gene and transposable element methylation in great tit (Parus major) brain and bloodCHG and CHH methylation sequence motifs. Occurrence of nucleotides are given (bits) relative to the distance from the C nucleotide. CpA sites are predominantly methylated (methylation level >10Â %) at both CHG and CHH sites, whereas methylated CpC sites are very rare. Cytosine is the most dominant third nucleotide at CHH methylated sitesBack to article page
