The correct answer for the given question is (D) radioactive DNA is found inside the infected cell and radioactive protein was found in the medium outside the cell. This demonstrates that DNA carries virus genetic information.
Explanation:
Harshey and chase conducted an experiment on bacteriophage in 1951 the bacteriophages that are used are responsible for infecting bacteria. they found that genes are not made up of protein but DNA.
This is an experiment that used the method known as isotope labeling. They tag DNA with Phosphorus and protein with sulfur as the coat of bacteriophages are also made up of protein. They found out the DNA of bacteriophages is inserted into bacteria while the protein coat remains outside in the medium. It means that only DNA is what transfer not the protein.
