Guanine and Cytosine are nucleic bases that pair together during DNA replication and during the translation of DNA to RNA.

Guanine is classified as a purine; it is a double ring structure.

Cytosine is classified as a pyrimidine; it is a single ring structure.

To form bonds purines can only pair with pyrimidines.
