If Meselson and Stahl had observed one intermediate, slightly smeared band after growing bacteria in the presence of ¹⁵N for one generation, and then after two generations in ¹⁴N again had found one slightly smeared band, they would most likely have concluded that DNA replicates A) semiconservatively. B) conservatively. C) semidiscontinuously. D) dispersively. E) semicontinuously.
