The specific pattern of hydrogen bonding between guanine and cytosine also contributes to the specificity of base pairing, ensuring that the genetic code is maintained across generations. Guanine can ...

The guanine residues form hydrogen bonds with the guanidinium groups ... The crucial nature of the contacts between cytosine methyl groups and the protein is underscored by mutational analysis ...

The thymine-adenine (T-A) base pair is held together by fewer hydrogen bonds compared to the guanine-cytosine (G-C) base pair, which has three hydrogen bonds. The complementary base pairing in DNA ...

and guanine binds to cytosine (G-C). The researchers believe that these new structures "are created due to the formation of ...
