Answer :
Both strong bonds (covalent and ionic) and weak interactions (van der Waals forces) are important in the function of chemical molecules in an organism.
What are the interactions in living organisms?
Now we know that organisms have various kinds of chemical interaction within them. These different kinds of interactions are responsible for the diverse properties we see in the organisms.'
Let us take the DNA molecule for instance, the atoms that compose the bases in the DNA molecule are all held together by covalent interactions. These are strong bonds.
On the other hand, the secondary structure of the DNA molecule owes to the hydrogen bonds and van der Waals forces that occur between the complimentary base pairs that we find in the DNA molecule.
