DNA methylation patterns

DNA methylation involves adding tiny chemical groups called methyl groups to specific sites on DNA. This process can regulate gene activity without changing the DNA sequence itself. When methyl groups attach to certain regions, they often turn genes off or reduce their activity, functioning like a dimmer switch for gene expression. These patterns are influenced by factors like age, environment, and lifestyle and play key roles in development, health, and disease. Overall, DNA methylation is a vital mechanism that helps control how our genes are expressed in different cells and conditions.
