... only of one carbon and three hydrogen atoms) on a cytosine base adjacent to the damaged site. Without this methyl group, the bulky chemical carcinogen resides at an external binding site in the minor groove of the DNA double helix.

...bases: adenosine (A), thymine (T), guanine (G) and cytosine (C). A always pairs with T, and G with C. To copy itself, the DNA molecule unwinds and splits. Either strand is now a template to build a new DNA molecule.
