Who, in which year showed firm enzymological proof that DNA alone functions as the template for the synthesis of new DNA strands? Correct Answer Meselson and Stahl in 1958

Within five years of the discovery of the double helix, evidence emerged for the separation of the complementary strands during DNA replication as suggested by Watson and Crick. This firm enzymological proof was first provided by Meselson and Stahl’s experiment of Semiconservative way of replication of DNA in 1958.

A bacterial culture (200 μL containing 1.8 × 109 cells) was treated with an antibiotic Z (50 μg per mL) for 4 h at 37°C. After this treatment, the culture was divided into two equal aliquots.
Set A: 100 μL was plated on Luria agar.
Set B: 100 μL was centrifuged, the cell pellet washed and plated on Luria agar.
After incubating these two plates for 24 h at 37°C, Set A plate showed no colonies, whereas the Set B plate showed 0.9 × 109 cells. This experiment showed that the antibiotic Z is
