Guanosine (GUA) is a natural biomolecule found in DNA and RNA that is formed by the combination of two ring systems, namely guanine (top) and ribose (bottom). In DNA the ribose ring is the 2'-deoxy form. It becomes incorporated into these nucleci acids via 5'-phosphorylated derivatives. In duplex DNA, guanosine is base-paired with a cytosine base (cytodine) on the opposite DNA strand.
