When meselson and stahl performed their experiments on dna replication, they grew cultures of e. coli in a heavy isotope of nitrogen (15n), then transferred cultures to a light isotope of nitrogen (14n) and allowed the cultures to grow in the latter for one or two generations. if replication occurred through a conservative mechanism, which of the following results would they have obtained?
