guanine
Guanine goes with Cytosine
No. Adenine doesn't even usually pair with Cytosine. If you're talking about DNA, Adenine pairs with Thymine and Cytosine pairs with Guanine. A with T, C with G. This is only a general rule, however- Adenine and Cytosine can pair if you have a wobble base pair.

Cytosine binds [bonds] with Guanine.

CYTOSINE!
Adenine and Uracil, which pair together (Uracil takes the place of Thymine from DNA) Guanine and Cytosine, which also pair together
Cytosine (C) and Guanine (G) pair, as do Adenine (A) and Thymine (T).
Guanine pairs with Cytosine on the human DNA double helix. Adenine pairs with Thymine.
