Summary Introduction
Introduction:
Degeneration of an organ system is called as senescence. Degeneration occurs after the age of highest functional efficiency, such as reduced ability to repair damage, increased susceptibility to disease, gradual loss of reserve capacities, and compensation for stress. Unrepaired damage of the DNA is a leading theory of senescence. Generally, in a mammalian cell, the DNA undergoes a predictable 10,000 to 100,000 damaging events per day. Particularly, the oxidative stress from free radicals produced by the cell’s own
