Guanine is one of the five main nucleobases found in the nucleic acids DNA and RNA.

The others are adenine, cytosine, thymine, and uracil. With the formula C5H5N5O, guanine is a derivative of purine.

Basic principlesEdit

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.
