Q. Which of the following statements about Hershey and Chase experiment are correct?
I. Sulphur is present in proteins, but not in DNA.
II. Phosphoms is present in DNA, but not in proteins.
III. ${}^{32}P$ will end up in the supernatant after centrifugation.
IV. Progeny generation of $T_2$ -bacteriophage contains ${}^{32}P$.

Molecular Basis of Inheritance

Solution:

Statements I, II and IV are correct.
Statement III is incorrect and can be corrected as ${ }^{35} S$ will end up in the supernatant after centrifugation as sulphur is present in proteins.
