In trying to determine whether dna or protein is the genetic material, hershey and chase made use of which of the following facts?
a) dna contains phosphorus, but protein does not
b) dna does not contain sulfur, whereas protein does.
c) dna contains nitrogen, whereas protein does not.
d) a and b only
e) a, b, and c

A and B only.

Explanation:

DNA is present as the genetic material of the living organism. Hershey and Chase experiments confirmed that only DNA is transmitted from one generation to the next generation.

They used radioactive phosphorus and sulfur and infects the cells with bacteriophage. The radioactivity labelled with phosphorus is present in the next generation whereas the radioactive sulfur molecules are not present in the next generation. DNA contains phosphorus whereas sulfur is present in the proteins.

Thus, the correct answer is option (D).
