WebElizabeth J. Radford, in Progress in Molecular Biology and Translational Science, 2024 2.1 DNA Methylation. DNA methylation involves the addition of a methyl group to the fifth carbon in the cytosine pyrimidine ring. In vertebrate somatic tissues this largely occurs symmetrically on the two strands in CpG dinucleotides, although appreciable levels of … WebThough CpG sites constitute a miniscule fraction of the genome (e.g., < 2%), CpG-rich regions, or CpG islands, are interspersed and associated with 70% of annotated gene promoters [45]. CpG islands are stretches of DNA (ranging from 300 to 3000 base pairs long) with a GC content greater than 50% and a ratio of CpG to GpC that is greater than …
