Aging Negatively Impacts DNA Repair and Bivalent Formation in the C. elegans Germ Line

Abstract excerpt

Defects in crossover (CO) formation during meiosis are a leading cause of birth defects, embryonic lethality, and infertility. In a wide range of species, maternal aging increases aneuploidy and decreases oocyte quality. In C. elegans which produce oocytes throughout the first half of adulthood, aging both decreases oocytes quality and increases meiotic errors. Phenotypes of mutations in genes encoding...
