In a regular watson-crick double helix base pairing DNA, guanine always pairs opposite cytosine. However this rule holds good only for double helical DNA, as, it is seen in tRNA that guanine (in the anticodon) pairs with cytosine as well as uracil of the corresponding codon in mRNA.
Guanine
Cytosine, a pyrimidine (sugar) base, pairs with Guanine, a purine (nitrogen) base.
Adenine always pairs with thymine in a DNAmolecule.
Adenine always pairs with thymine Cytosine always pairs with guanine.
There are equal parts of guanine and cytosine, and adenine and thymine, because they form base pairs in the DNA molecule. This is in accordance with the base-pairing rule, which states that in DNA, adenine always pairs with thymine, and guanine always pairs with cytosine.
In a DNA molecule cytosine always pairs with guanine, the same is true for an RNA molecule.
Guanine
Cytosine.

Adenine is complimentary to thymine. Cytosine is complimentary to guanine.
The nitrogenous base, Cytosine, pairs with the nitrogenous base, Guanine.In DNA:Cytosine - GuanineAdenine - ThymineIn RNA:Cytosine - GuanineAdenine - Uracil
