Your DNA is like the blueprint for your body. It contains the instructions that code for all the proteins, enzymes, and structures that make you who you are. However, just like a blueprint can be damaged, altered, or incomplete, your DNA can also be affected by various factors, such as environmental toxins, oxidative stress, radiation, or errors in replication. These damages can lead to mutations, epigenetic changes, or functional impairment, that may increase your risk of diseases, aging, or infertility.
