WebDec 23, 2001 · Introduction. CpG islands of vertebrates are DNA regions that contain a high frequency of CpG dinucleotides relative to their occurrence in the bulk genome, in which a CpG doublet occurs at only one fifth of the frequency that would be expected from the G + C content (Bird, 1987; Cross and Bird, 1995; Gardiner-Garden and Frommer, 1987; Larsen … WebJan 16, 2014 · CpG Islands CpG islands (CGI) are genomic regions that contain a high concentration of CpG sites. 4.

http://www.urogene.org/cgi-bin/methprimer/methprimer.cgi WebDefinition. CpG islands are short stretches of DNA with an unusually high GC content and a higher frequency of CpG dinucleotides (cytosine 5′ to a guanine, separated by a phosphodiester bond) compared to the rest of the genome. CpG islands account for about 1–2% of the genome and are usually located in the 5′ regulatory regions of genes.
