Explanation:
Free radicals are the atoms produced in the cell mainly due to oxidative stress. For example, oxygen splits into an atom having an unpaired electron. So these atoms having unpaired electrons are called free radicals.
Free radicals are responsible for damaging DNA and causing cancers in the body. In our cells antioxidants are present which checks the presence of free radicals in the cell.
