class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>DNA methylation refers to the <strong>addition of a methyl group (CH\u2083)<\/strong> to DNA molecules, typically at cytosine bases located next to

class=\"ez-toc-section-end\"><\/span><\/h3>\n<p>The process usually occurs at <strong>CpG sites<\/strong>, regions of DNA where cytosine and guanine appear together.

Instead of changing the DNA sequence itself, this process modifies how genes are turned on or off. It plays a central role in development, aging, and disease. Advances in genomics have shown that abnormal methylation patterns influence cancer, metabolic disorders, and neurological conditions. Understanding this mechanism is essential for modern biomedical research and precision medicine. What Is DNA Methylation? DNA methylation refers to the addition of a methyl group (CH\u2083) to DNA molecules, typically at cytosine bases located next to guanine nucleotides.
