What would happen if the bases in DNA strands were connected by a bond other than a hydrogen bond?
tekilochka [14]
The correct answer is It would be more difficult for DNA to unzip since it would require more energy to break the bonds.

That is because it would most probably be a covalent bond and such a bond is stronger than a hydrogen bond which means that more energy would be needed to break it.
