Answer:
Structural Biochemistry/Chemical Bonding/Hydrogen bonds. ... The hydrogen atom in a hydrogen bond is shared by two electronegative atoms such as oxygen or nitrogen.) Hydrogen bonds are responsible for specific base-pair formation in the DNA double helix and a major factor to the stability of the DNA double helix structure.Hydrogen bonding is important because it is crucial to all life on Earth. Here are three reasons why hydrogen bonding is important. DNA has a double-helix structure because hydrogen bonds hold together the base pairs in the middle. Without hydrogen bonds, DNA would have to exist as a different structure.A hydrogen bond (often informally abbreviated H -bond) is a primarily electrostatic force of attraction between a hydrogen (H) atom which is covalently bound to a more electronegative atom or group, particularly the second-row elements nitrogen (N), oxygen (O), or fluorine (F)—the hydrogen bond donor (Dn)—and another ...Hydrogen bonds in water provide many characteristic benefits to water: cohesion (holding water molecules together), high specific heat (absorbing heat when breaking, releasing heat when forming; minimizing temperature change), high heat of vaporization (several hydrogen bonds must be broken in order to evaporate water)
