As you know from the Lewis model, such molecules are not chemically stable and will quickly react with other molecules. According to some theories, free radicals may attack molecules within the cell, such as DNA, changing them and causing cancer or other diseases. Free radicals may also attack molecules on the surfaces of cells, making them appear foreign to the body’s immune system. The immune system then attacks the cells and destroys them, weakening the body. Draw Lewis structures for the free radicals implicated in this theory of aging, which are given here. a. O2 -b. O- c.
