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.
Origin
The study of DNA repair pathways is rooted in molecular biology and genetics, gaining prominence with the discovery of DNA’s structure and the subsequent realization of its constant vulnerability to damage from both internal and external stressors. The fundamental mechanisms were largely elucidated through decades of research, culminating in the 2015 Nobel Prize in Chemistry for work detailing the molecular mechanisms of several repair processes. This field highlights the evolutionary imperative for biological systems to safeguard their genetic blueprint.
Mechanism
Multiple, distinct mechanisms operate to address different types of damage, including Base Excision Repair (BER) for single-base damage and Nucleotide Excision Repair (NER) for bulky lesions like those caused by UV light. More complex breaks, such as DNA double-strand breaks, are repaired by Homologous Recombination (HR) or Non-Homologous End Joining (NHEJ). These pathways involve a highly coordinated sequence of enzyme activities that excise the damaged segment, synthesize the correct replacement sequence using the complementary strand as a template, and ligate the final piece back into the helix, thereby ensuring the genetic code remains intact.
