Target entity: Gurdon experiment
Context triple: [John B. Gurdon, knownFor, Gurdon 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. Hershey–Chase experiment
    The Hershey–Chase experiment was a landmark 1952 study in molecular biology that used bacteriophages to demonstrate that DNA, rather than protein, is the genetic material.
  • C. Dulbecco
    Dulbecco is the surname of Renato Dulbecco, an Italian virologist and Nobel Prize laureate recognized for his pioneering work on the interaction between viruses and the genetic material of cells.
  • D. von Baer’s laws of embryology
    Von Baer’s laws of embryology are a set of principles in developmental biology stating that general features of a group of animals appear earlier in embryonic development than specialized features, and that embryos of different species diverge rather than pass through adult stages of other species.
  • E. Ashra experiment
    The Ashra experiment is a high-energy astrophysics observatory project in Hawaii designed to detect cosmic rays, gamma rays, and neutrinos using wide-field optical imaging techniques.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
