CpG Islands
There are regions of the genome that have a higher concentration of CpG sites, known as CpG islands. Many genes in mammalian genomes have CpG islands associated with the start of the gene (promoter regions). Because of this, the presence of a CpG island is used to help in the prediction and annotation of genes.

Famous quotes containing the word islands:
“we are so many
and many within themselves
travel to far islands but no one
asks for their story....”
