DNA contains many hydrogen bonds. Are hydrogen bonds stronger or weaker than covalent bonds? What are the consequences of this difference in strength?

Summary Introduction

To determine: Whether hydrogen bonds are stronger or weaker than covalent bonds in DNA.

Introduction: In nature, atoms are combined to form molecules by means of chemical bonding. Each chemical bond has a different nature in terms of strength and its contribution to the shape and function of a biological molecule.

Explanation of Solution

A type of atomic interaction which involves a weak interaction is known as ‘hydrogen bond.’ Hydrogen bonds show weaker interaction than covalent bonds. In hydrogen bonds, two atoms carry partial charges but are in the opposite direction, which causes less bond energy in hydrogen bonds.

Hydrogen bonds are weak, and they can easily be broken...
