Oxidative stress refers to a pathological state that arises from the damage caused by free radicals (collectively known of as reactive oxygen species, ROS) when they interact with molecules in the body. These free radicals can damage any component of the cell such as the DNA, the proteins and the lipids and give rise to cancer and various other disease states such as heart disease and neurodegenerative disorders. | Oxidative stress refers to a pathological state that arises from the damage caused by free radicals (collectively known of as reactive oxygen species, ROS) when they interact with molecules in the body.

Many experiments clearly provide evidences that DNA and RNA are susceptible to oxidative damage. It has been reported that especially in aging and cancer, DNA is considered as a major target..<ref>[http://www.news-medical.net/health/Oxidative-Stress-and-Oxidants.aspx Oxidative Stress]</ref> | |||
