Base-Pairing. The bases in DNA do<span> not pair randomly. ... The base-pairing rules state that A </span>will<span> always bind to T, and G </span>will<span> always bind to C (Figure below). For example,</span>if one DNA strand reads<span> ATGCCAGT, the other </span>strand will<span> be made up of the</span>complementary<span> bases: TACGGTCA</span>
