Methods researchers use to study DNA methylation
By: Alicia M Prater PhD
DNA methylation is a modification of DNA that occurs after synthesis of the strand. A methyl group (CH3) is added to one of the four nucleotides in DNA, specifically cytosine, by the enzyme DNA methyltransferase. This chemical change has been found to occur in CpG...
