Mesel and Stahl Experiment.mp4

The Meselson--Stahl experiment was an experiment by Matthew Meselson and Franklin Stahl in 1958 which supported the hypothesis that DNA replication was semiconservative. Semiconservative replication means that when the double stranded DNA helix was replicated, each of the two double stranded DNA helices consisted of one strand coming from the original helix and one newly synthesized. It has been called "the most beautiful experiment in biology

Like if u clicked on the correct model.

@losttya When it was in the n15 solution it could only make itself out of n15, and so both the stands it made were 'heavy'. When it was in the n14 solution (for the second generation) it would split each DNA molecule in half so you would have four single strands (A,B,C,D), A and B would be made from n15, C and D would be made from n14, so when a new strand was made you would get two n15-n14 hybrids (from A and B) and two completely n14 molecules (C and D) becuase n14 is all it can be made from.

why we got in generation 2 a hybrid stands of n15 and n14, when we should get 2 strands of n14 and 2 strands of n15
