The results will be inconclusive because $^{15}N$ is incorporated into both $DNA$ and proteins.

Vedclass · Answer

(B) The use of $^{15}N$ is inappropriate because the detection methods for $^{32}P$ and $^{15}N$ differ. $^{32}P$ is a radioactive isotope,whereas $^{15}N$ is a stable,heavier isotope of nitrogen,not a radioactive one.Even if $^{15}N$ were radioactive,it would not provide conclusive results because nitrogen is a fundamental component of both $DNA$ (in nitrogenous bases) and proteins (in the amino groups of amino acids).Therefore,if $^{15}N$ were used,it would be detected in both the bacterial cell pellet and the supernatant,making it impossible to distinguish whether the genetic material transferred was $DNA$ or protein.

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