Guanine, along with adenine and cytosine, is present in both DNA and RNA, whereas thymine is usually seen only in DNA, and uracil only in RNA. Guanine has two tautomeric forms, the major keto form (see figures) and rare enol form. It binds to cytosine through three hydrogen bonds.
Cytosine is a nitrogen bases that is found in the DNA. There is four nitrogen bases and this is one of them. The amount of cytosine in cells always equals the amount of guanine, and the amount of adenine always equals the amount of thymine. 3 people found this useful.
