Who Performed Classic Experiments That Supported the Semiconservative Model of DNA

Question

Who performed classic experiments that supported the semiconservative model of DNA replication?
A)Watson and Crick
B)Meselson and Stahl
C)Hershey and Chase
D)Franklin and Wilkins
E)Avery

Accepted Answer

Meselson and Stahl performed experiments in which they grew bacteria in a medium containing a heavier isotope of nitrogen. They then transferred the bacteria to a medium containing the normal, lighter isotope. By analyzing the DNA after each generation, they were able to show that the DNA replicated in a semiconservative manner. This provided strong evidence for the model proposed by Watson and Crick.
