Answer: The correct answer is -
The weakness of hydrogen bonds between the bases of DNA allows the two strands to separate from one another so that the template strands can be exposed for the process of DNA replication.
Step-by-step explanation:
The hydrogen bonds are considered as weak, noncovalent interactions that hold the complementary bases of two strands of DNA together.
They are weak interactions that allows the separation of two DNA strands, so that template DNA can be for formation of new DNA molecules (DNA replication).
The template DNA is used by DNA polymerase, which adds dNTPs (deoxyribonucleoside triphosphates) in a complementary manner.
