Matthew Meselson and Franklin Stahl are two biologists who prove that DNA replication was semiconservative.
At the time, many strong evidences from experiments using bacterial viruses had already convinced most scientists that DNA was the molecule of heredity; however they knew little about the DNA replication process. After the dimensionally accurate model building by Watson and Crick, it was clear that the process of replication and information distribution have to use the DNA from parent cell as template to achieve an orderly flow of genetic inheritance to daughter cells. However the model of Watson and Crick still cannot fill the missing information about how DNA might accomplish replication.
Before the Meselson-Stahl experiment, many researches have been done on the problem of DNA replication by other scientists, but all of those efforts were ineffective or not directly relate to the replicate process. There were three hypotheses suggested; which are Semi-Conservative,......
