DNA Repair Pathways

Meaning

DNA repair pathways represent a sophisticated collection of cellular processes that constantly monitor, identify, and correct molecular damage to the DNA molecules that encode the organism’s genome. These pathways are absolutely vital for maintaining genomic integrity, which directly correlates with cellular function, organismal healthspan, and longevity. When the rate of DNA damage exceeds the capacity of these repair systems, the accumulation of errors can lead to cell dysfunction, senescence, or malignant transformation.
