Mechanism of BRCA1-BARD1 function in DNA end resection and DNA protection - Nature

DNA end resection is a multi-step process vital for DNA repair, involving interplay between key proteins and complexes.

DNA strands show symmetry in damage tolerance but asymmetries in repair efficiency

DNA strands are replicated and repaired asymmetrically, influencing mutation rates.

DNA-repairing animals may unlock anti-aging treatments in NEXT DECADE

DNA repair is key to longevity in animals like elephants, whales, and jellyfish.
Scientists are working to recreate these DNA repair abilities in humans to delay age-related conditions.
