Final answer:
The Hershey-Chase experiment concluded that DNA was the genetic material after finding that radioactive phosphorus (DNA marker) was inside the bacteria cells, while radioactive sulfur (protein marker) was not.
Step-by-step explanation:
The Hershey-Chase blender experiment provided evidence that genetic material was DNA, not protein. They used two sets of T2 bacteriophages: one batch labeled with radioactive sulfur (35S) to tag proteins and another with radioactive phosphorus (32P) to tag DNA.
When they blended the phage-infected bacterial cells to detach the phage coats, they found that the 35S was in the supernatant with the detached coats, while the 32P was in the pellet with the cells, indicating that it was the DNA introduced to the cells. Therefore, the Hershey-Chase experiment showed that material from bacteriophage labeled with radioactive sulfur did not remain with the transduced bacteria, leading to the conclusion that DNA was the genetic material.
