Study says mothers pass on ‘aging gene’

Mothers play a crucial role in determining how quickly their children grow old by passing on genetic mutations that speed up the aging process leading to a shorter lifespan, a study suggests.

Scientists have found that inherited mutations in the DNA of the mitochondria – the tiny “power packs” of the cells that are always inherited solely from mothers – can accelerate aging in mice.

A study has shown that when mutations are artificially created in mitochondrial DNA, the resulting offspring of the affected female mice aged significantly faster than the offspring of unaffected females.
