Two identical DNA molecules result from the replication process, with one original strand and one new strand. This process is called semi-conservative replication. It is important to understand that semi-conservative replication is a complex, enzyme-controlled reaction. To understand just how complex DNA replication can be, it must be stated that deoxyribose is a five-carbon sugar. Chemists number the carbon atoms, 1 to 5.
Meselson and Stahl confirmed the DNA replication is semiconservative when they found only hybrid (intermediate density) DNA in bacteria after first growing them in a medium with heavy nitrogen and then switching them to a light nitrogen.
