Semiconservative replication

Semiconservative replication describes the method by which DNA is replicated in all known cells. This method of replication was one of three proposed models of DNA replication: The deciphering of the structure of DNA by Watson and Crick in 1953 suggested that the semiconservative model was correct (as Watson and Crick pointed out in a sly one-line concluding sentence to their seminal paper). This was soon verified by Meselson-Stahl experiment.
