Suppose you are a biologist trying to discover how DNA copies itself. You grow cells in a culture that contains a special isotope of nitrogen, N-15, which will become part of any new DNA the cell makes. After one generation, you analyze the DNA and find that all the DNA has N-15. You then take those cells and grow them for another generation in a culture with the normal isotope of nitrogen, N-1. You know half of the DNA has only N-15 and half has only N-14. What can you infer from this information about how DNA replicates? Explain your reasoning.
