Human eggs are protected from age-related genetic mutations, mtDNA study finds

As we age, the genes in our cells accumulate more mutations. This is one of the contributory factors to age-related diseases and the aging process. However, in a new study published in Science Advances, researchers have discovered one exception where genetic mutations don’t appear to build up as humans get older—the mitochondrial DNA (mtDNA) of human egg cells in women.
