"WebHowever, methylation is often suppressed in the promoter regions of active genes, and therefore one can find there regions with much higher CG frequency than elsewhere in the genome. Such regions are important signals for gene finding, and they are called CpG islands. Often, CpG islands are modeled by a Hidden Markov Model similar to the Fair ... " - Cpg island hmm
