DNA is the source code of life.  It is the literal set of instructions for our bodies.  However, over time it degrades.  Allowing for errors to occur, known as mutations.  This degradation is what leads to the physical signs of aging.  Is there anything we can do to prevent this DNA degradation?

Mitochondrial Mutations

A mitochondrion is a cellular organelle that serves as the site for cellular respiration and energy production (ATP or Adenosine Triphosphate). It is a double-membrane-bound organelle and is only present in eukaryotic cells.
