Life is impossible without DNA repair
"DNA Repair Machines
All the information for heredity is encoded in DNA molecules that are constantly under attack from sources inside and outside the body—by sunlight, ionizing radiation, other environmental carcinogens, and free radicals from the normal cellular metabolism. Surprisingly, most of this damage comes from the chemical reactions that are the normal processes needed for life, so life is impossible without DNA repair even in the absence of environmental toxins."
