Question

Answer the following question based on Hershey and Chase's experiments.
State the conclusion drawn by them after the experiments.

Answer 1

1. Hershey and Chase based on their experiment concluded that DNA, not protein, was the genetic material.
   
2. They determined that a protective protein coat was formed around the bacteriophage, but it was the internal DNA which conferred its ability to produce progeny inside a bacteria.
   
3. They showed that, in growth, protein has no function, while DNA has some function. They determined this from the amount of radioactive material remaining outside of the cell. Only 20% of the 32-P remained outside the cell, demonstrating that it was incorporated with DNA in the cell's genetic material.
   
4. All of the 35-S in the protein coats remained outside the cell, showing it was not incorporated into the cell, and that protein is not the genetic material.
