The Diameter of DNA is maintained due to _.
Correct answer: D. H-bond
- A. Dipole dipole forces
- B. Induced dipole forces
- C. Chemical bond
- D. H-bond
Explanation
The base pairing, i.e. H-bond stabilizes the three-dimensional structure of DNA, i.e. the diameter of DNA also. The bases in DNA can interact via hydrogen bonds. The two strands of the DNA molecule are held together with the help of a hydrogen bond.

About Hydrogen Bonding
Hydrogen bonding is the strong attraction between hydrogen attached to nitrogen, oxygen or fluorine and an electronegative atom in the same or another molecule. It explains unusual boiling points, viscosity, surface tension, water's properties and the difference between intermolecular and intramolecular hydrogen bonding.
