I need help. We know that promoters mostly contain CpG island. There are CGI-containing promoters containing genes and CGI-less promoters containing genes. Is this phenomenon tissue specific? I mean if suppose gene X (suppose it is not a housekeeping gene) is CpG rich, will it be CpG rich in all tissues?
Please help me how can I get extensive information regarding this.
