methylome

The methylome refers to the complete set of chemical modifications called methyl groups added to the DNA molecule in an organism. These modifications can influence how genes are turned on or off without changing the underlying DNA sequence. Methylation helps regulate various biological processes, including development, cell differentiation, and responses to the environment. Essentially, the methylome provides an additional layer of information on how genes are used and controlled in our bodies. It plays a crucial role in health, disease, and aging by impacting gene activity.
