The hydrogen bonds in DNA Watson–Crick base pairs have long been considered predominantly electrostatic phenomena. In this chapter, we show with state-of-the-art calculations that this is not true and that electrostatic interactions and covalent contributions in these hydrogen bonds are in fact of...

Hydrogen bonding between complementary base pairing in the DNA double helix provides excellent stability to the structure, whereas in protein, the interaction between groups such as NH, CO, and OH is important in predicting regular helical or sheet conformation. Hydrogen bonds are relatively weak in...

Hold together the two strands of DNA Bind transcription factors to each other Hydrogen Bonding in Water Although hydrogen bonds form between hydrogen and any other electronegative atom, the bonds within water are the most ubiquitous (and some would argue, the most important). Hydrogen bonds form ...
Covalent bonds and hydrogen bonds are primary intermolecular forces. Covalent bonds can occur between most elements on the periodic table. Hydrogen bonds are a special bond between a hydrogen atom and an oxygen, nitrogen or fluorine atom.
Hydrogen bonding greatly affects our biology. Numerous examples in biochemistry show how important hydrogen bonding is. In DNA, hydrogen bonds between nitrogenous bases in nucleotides on the two strands of (guanine pairs with cytosine, adenine with thymine) give rise to the double-helix structure tha...
