Q. 11. You are repeating the Hershey-Chase experiment and are provided with two isotopes (in place of in the original experiment). How does you expect your results to be different?
Use of will be inappropriate because the method of detection of different ( being a radioactive isotope while is non-radioactive but is the heavier isotope of nitrogen).
Even if was radioactive then its presence would have been detected, both inside the cell ( incorporated as a nitrogenous base in DNA) as well as in the supernatant, because would also get incorporated in amino group of amino acids in proteins. Hence, the use of would not give any conclusive results.
