abstract：:Unmethylated CpG rich islands are a feature of vertebrate DNA: they are associated with housekeeping and many tissue specific genes. CpG islands on the active X chromosome of mammals are also unmethylated. However, islands on the inactive X chromosome are heavily methylated. We have identified a CpG island in the 5' r...
