Calorie restriction reveals a potential way to slow age-related DNA mutations

Caloric restriction reduces genetic mutations across the mouse genome

Mutations are changes in the molecular "letters" that make up DNA, the genetic blueprint for cells. Mutations build up with age in every cell when DNA is damaged or when cells make mistakes in fixing or copying it.

Calorie restriction reveals a potential way to slow age-related DNA mutations

Mutations are changes in the molecular "letters" that make up DNA, the genetic blueprint for cells. Mutations build up with age in every cell when DNA is damaged or when cells make mistakes in fixing or copying it. Most mutations are harmless, but when they disrupt genes, they can cause cancer and other diseases.
