Bonds between linking nitrogenous bases of two DNA strands are Hydrogen bonds with 3 H-bonds connecting cytosine and guanine and 2 H-bonds connecting adenine and thymine, while the bonds between the stacking of DNA are kept in close contact via van der waals interactions.
A hydrogen bond is an extremely strong bond between molecule s with a Hydrogen atom bonded to a Fluorine, Oxygen or Nitrogen atom and a molecule with a Fluorine, Oxygen or Nitrogen atom. Hydrogen bond s are notably found between the bases in DNA. Transcript ...Hydrogen bond. noncovalent bond between an electronegative atom (commonly oxygen or nitrogen) and a hydrogen atom covalently bonded to another electronegative atom. Particularly important in stabilizing the three-dimensional structure of proteins and formation of base pair s in nucleic acids.
