Noun
a purine base found in DNA and RNA; pairs with cytosine
Source: WordNetA base is attached to the 1' position, in general, adenine (A), cytosine (C), guanine (G), or uracil (U). Source: Internet
Adenine pairs with thymine (two hydrogen bonds), and guanine pairs with cytosine (stronger: three hydrogen bonds). Source: Internet
Adenine binds with thymine and uracil; Thymine binds only with adenine; and cytosine and guanine can bind only with one another. Source: Internet
Between 1882 and 1906, Fischer determined the structure and also showed that uric acid can be converted to guanine. citation Syntheses Trace amounts of guanine form by the polymerization of ammonium cyanide ( NHmain CN ). Source: Internet
Because of this intermolecular bonding, guanine is relatively insoluble in water, but it is soluble in dilute acids and bases. Source: Internet
BFA inhibits the function of several guanine nucleotide exchange factors (GEFs) that mediate GTP-binding of ARFs. Source: Internet
