... A CpG island consists of a stretch of some 300 to 3,000 DNA bases where clusters of cytosine and guanine dinucleotides make up about half the sequence 1 . More than 60% of these islands are associated with the promoter regions of genes and are not methylated in genes that are actively transcribed. ...
