Explain how did A. D. Hershey and M. J. Chase differentiate DNA and proteins in their experiment while proving that DNA is the genetic meterial?

Explain the experiment to prove that "Transfoming Principle" is DNA.

Define transformation in Griffith's experiment. Discuss how it helps in the identification of Dna as the genetic material.

Recall the experiments done by Frederick Griffith, Avery, MacLeod and McCarty, where DNA was speculated to be the genetic material. If RNA, instead of DNA was the genetic material, would the heat killed strain of Pneumococcus have transformed the R- strain into virulent strain? Explain

Give an account of Hershey and Chase experiment. What did it conclusively prove? If both DNA and proteins contained phosphorusand sulphur do you think the result would have been the same?

You are repeating the Hershey-Chase experiment and are provided with two isotopes: 32P and 15N (in place of 35S in the original experiment). How do you expect your results to be different?
