CpG site: Characters, Regions & Measurement

The CpG sites or CG sites are regions of DNA where a cytosine nucleotide is followed by a guanine nucleotide in the linear sequence of bases along its 5' → 3' direction. CpG sites occur with high frequency in genomic regions called CpG islands. CpGs are the common unit of methylation because their information is double stranded (the GpC complement is…
