DNA Repair

Meaning

DNA repair refers to a collection of highly sophisticated cellular processes that monitor and correct damage to the deoxyribonucleic acid molecules that encode the genome. These essential mechanisms continuously counteract the detrimental effects of endogenous metabolic byproducts, such as reactive oxygen species, and exogenous environmental factors, including UV radiation and chemical exposure. Maintaining genomic integrity through effective DNA repair is fundamentally linked to cellular survival, preventing mutagenesis, and influencing the rate of biological aging.
