islas ricas en CpG
islas ricas en citosina-fosfato-guanina
Scope note: Áreas con un incremento de densidad de la secuencia de dinucleótidos citosina-éster fosfato-guanina. Forman filamentos de ADN de entre varios cientos hasta varios miles de pares de bases de longitud. En los seres humanos existen alrededor de 45.000 islas CpG, la mayoría de ellas situadas en los extremos 5' de los genes. Se encuentran no metiladas, excepto en el caso de los del cromosoma X inactivo y algunas asociadas con genes impresos.

Scope note: Areas of increased density of the dinucleotide sequence cytosine--phosphate diester--guanine. They form stretches of DNA several hundred to several thousand base pairs long. In humans there are about 45,000 CpG islands, mostly found at the 5' ends of genes. They are unmethylated except for those on the inactive X chromosome and some associated with imprinted genes.
