DNA methylation
DNA methylation is a biological process where small chemical groups called methyl groups attach to DNA molecules, affecting how genes are expressed. This modification doesn't change the DNA sequence itself, but it influences whether genes are turned on or off. Methylation plays a crucial role in regulating development, tissue differentiation, and gene activity throughout an organism's life. It also has implications in aging and various diseases, including cancer. By studying DNA methylation patterns, scientists can gain insights into how genes function and how environmental factors may impact our health.

DNA methylation is a biological process where tiny chemical tags, called methyl groups, are added to DNA molecules. This process can regulate gene activity by turning genes on or off without changing the underlying DNA sequence. Methylation usually occurs in regions of DNA that control gene expression. Changes in DNA methylation patterns can influence development, aging, and diseases like cancer. Essentially, it acts like a dimmer switch for genes, affecting how much or how little a gene is expressed, which plays a crucial role in how our bodies function and respond to the environment.
