Definition CpG is shorthand for 5'—C—phosphate—G—3' , that is, cytosine and guanine separated by only one phosphate group; phosphate links any two nucleosides together in DNA. The CpG notation is used to distinguish this single-stranded linear sequence from the CG base-pairing of cytosine … See more 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 … See more CpG islands in promoters In humans, about 70% of promoters located near the transcription start site of a gene (proximal promoters) contain a CpG island. Distal promoter elements also frequently contain CpG … See more CpG depletion has been observed in the process of DNA methylation of Transposable Elements (TEs) where TEs are not only … See more CpG islands (or CG islands) are regions with a high frequency of CpG sites. Though objective definitions for CpG islands are limited, the usual formal definition is a … See more In mammals, DNA methyltransferases (which add methyl groups to DNA bases) exhibit a sequence preference for cytosines within CpG sites.
