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:
“What are the islands to me
if you are lost
what is Naxos, Tinos, Andros,
and Delos, the clasp
of the white necklace?”
