In the Meselson-Stahl experiment, what happened after the E. coli was moved to the N14 medium and two rounds of cell division occurred? This result demonstrated that DNA replicated in a semi-conservative manner.  A. The DNA formed one band at the N15 density level and one band at the N14 density level.    B. The DNA formed one band between the N14 and N15 density levels and one band at the N14 density level.   .C. The DNA only formed one band between the N14 and N15 density levels.
