Answer:
The correct answer is (C) DNA
Explanation:
Bacteriophages are viruses that are known to infect bacteria. Viruses contain the genetic material in a proteinaceous capsid. The genetic material can be DNA or RNA.
During infection bacteriophage transfer the genetic material(DNA) in the bacterial cell and the protein coat remains outside the cell. So as the protein contain sulfur which is present in the protein coat of bacteriophage therefore radioactive sulfur will not be found in the bacterial cell.
Phosphorus is the part of DNA therefore if radioactive phosphorus is found in bacteria then it shows that the viral DNA is present in the infected bacteria. So the correct answer is DNA.
