The DNA can labeled with heavy nitrogen because DNA contains nitrogen bases inside the bases. The answer is E

Explanation:

Because DNA contains bases inside with phosphate and sugar. In the base part, there are many N molecules. When DNA is replicated, the newly synthesized bases labeled with heavy nitrogen and it will differ from the other strand.
