Who performed the blender experiment? What does this experiment prove? Describe the steps followed in this experiment?
The proof for DNA as the genetic material came from the experiments of Hershey & chase who worked with bacteriophages. The bacteriophage on infection injects only the DNA into the bacterial cell & not the protein coat. Bacterial cells treat the viral DNA as their own & subsequently manufacture more virus particles. They grew some viruses on a medium that contained radioactive Phosphorus & some others on a medium that contained radioactive sulfur. Viruses grown in the presence of radioactive phosphorus contained radioactive DNA but not proteins because DNA contains phosphorus. Similarly, viruses grown on radioactive sulfur contain radioactive protein because DNA does not contain sulfur.
