DNA CpG methylation service

    DNA methylation is an epigenetic modification, which is a DNA methyltransferase (DNA methyl-transferase, Dnmt)-catalyzed S-adenosylmethionine as methyl donor. the DNA in eukaryotes, 5 - methylcytosine is the only chemical modification of existing bases. CG dinucleotide is the most important methylation sites,  accounting for C in mammals mC total of 2-7%. In general, DNA methylation can inhibit gene expression.
