What was the conclusion drawn from the Hershey-Chase experiment?

Options

  1. AProteins are the genetic material
  2. BRNA is the genetic material
  3. CDNA is the genetic material
  4. DCarbohydrates are the genetic material

Correct answer

C. DNA is the genetic material

Step-by-step solution

Radioactive phages were allowed to attach to E. coli bacteria. Then, as the infection proceeded, the viral coats were removed from the bacteria by agitating them in a blender. The virus particles were separated from the bacteria by spinning them in a centrifuge. Bacteria which were infected with viruses that had radioactive DNA were radioactive, indicating that DNA was the material that passed from the virus to the bacteria. Bacteria that were infected with viruses that had radioactive proteins were not radioactive
