Target entity: Hershey–Chase experiment
Context triple: [Phage Group, contributedTo, Hershey–Chase experiment]
  • A. Luria–Delbrück experiment
    The Luria–Delbrück experiment was a landmark 1943 study in bacterial genetics that demonstrated mutations arise randomly rather than in response to selective pressure, providing key evidence for the genetic basis of evolution.
  • B. Alfred Hershey
    Alfred Hershey was an American bacteriologist and geneticist best known for the Hershey–Chase experiment, which helped establish DNA as the genetic material.
  • C. Oswald Avery
    Oswald Avery was a Canadian-American physician and molecular biologist best known for demonstrating that DNA is the material responsible for heredity.
  • D. Martha Chase
    Martha Chase was an American geneticist best known for the Hershey–Chase experiment, which demonstrated that DNA is the genetic material.
  • E. Miller–Urey experiment
    The Miller–Urey experiment was a landmark 1952 study that simulated early Earth conditions to demonstrate that organic molecules essential for life could form spontaneously from simple inorganic precursors.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
