Hershey-Chase Experiment DNA Evidence — NEET Biology
📚 Practice ConceptBacteria which was 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. This indicates that proteins did not enter the bacteria from the viruses. DNA is therefore the genetic material that is passed from virus to bacteria.
A bacteriophage infects E. coli and transfers only its DNA inside the host. Which experiment and evolutionary implication does this support?
View solution & NCERT explanation
Correct answer: B — Hershey & Chase experiment – DNA is genetic material
Hershey & Chase used radioactive P and S to prove DNA, not proteins, enter bacteria. This was key in establishing DNA as hereditary material.
