How are microbial communities assembled in the > 5,000 - y - old subsurface of marine sediment, and do they undergo adaptive evolution or
accumulate mutations due to impaired DNA repair under such energy - limited conditions?
Unfortunately, aging cells have a diminished ability to produce ATP
due to changes in mitochondrial structure and function — unless we intervene or support our cellular energy production.Research indicates that mitochondrial DNA
mutations begin
accumulating in individuals starting in their mid-thirties which contributes to the decreased energy that so many people experience with increasing age.
