Introduction DNA is the genetic material that provides instructions for the development, function, and reproduction of all living organisms. It is the molecular basis of life, and any damage to it can have serious consequences for the organism. DNA damage can occur spontaneously or as a result of exposure to environmental agents such as radiation, chemicals, and viruses. This damage can lead to mutations and ultimately to diseases such as cancer, aging, and neurodegenerative disorders. In order to maintain the integrity of the genetic material, cells have developed several mechanisms to repair DNA damage. These mechanisms are essential for ...
