DNA is composed of 5-carbon rings attached to each other in chains (in between the rings is a phosphate molecule attached to the 5’ carbon). The second ()2') carbon in the ring is where the bases are attached. Guanine pairs with Cytosine while Adenine pairs with Thymine.

Attached are two images concerning DNA.

The first image is a diagram that illustrates the base paring of DNA. First, there is the ribose-phosphate backbone that keeps the DNA together. Then the bases thymine and adenine are joined together by two hydrogen bonds. On the other hand, the bases guanine and cytosine are joined together by three hydrogen bonds.

The second image shows the helical structure of the DNA.
