Meselson-Stahl experiment differentiating between three models of
Introduction:
Meselson-Stahl experiment was proposed by two scientists called Matthew Meselson and Franklin Stahl. In 1958, they supported Watson and Crick experiment which stated replication of genetic material called DNA (deoxyribonucleic acid) is semiconservative.
