A theory that our cells have molecular clock processes ticking inside them, that damage DNA by generating mutations continuously throughout life, has just been proven.These clock-like mutational processes could ultimately be responsible for a large proportion of human cancer and aging. 2 clock-like mutational processes have been found in human cells and the rates at which the two clocks tick in different human cell types have been determined.

Every cell in the human body contains a copy of the human genome...
