The base pairing rules<span> for </span>DNA<span> are governed by the complementary </span>base pairs<span>: adenine (A) with thymine (T) in an A-T </span>pairing<span> and cytosine (C) with guanine (G) in a C-G </span>pairing<span>. Conversely, thymine only binds with adenine in a T-A </span>pairing<span> and guanine only binds with cytosine in a G-C </span>pairing<span>.</span>
