US supercomputer with 200,000 trillion moves per second shows how DNA repairs itself

Scientists have made significant discoveries about the Nucleotide Excision Repair (NER) complex, a crucial DNA repair mechanism. Using supercomputer simulations, they revealed NER's three-stage process: recognition, verification, and repair. The research provides insights into how mutations in NER proteins can lead to genetic disorders like xeroderma pigmentosum and Cockayne syndrome. This improved understanding of NER's function may help in developing treatments for these conditions and advancing our knowledge of DNA repair processes.
