Target entity: Hershey–Chase experiment Context triple: [Alfred Hershey, notableWork, Hershey–Chase experiment]
-
A.
Hershey–Chase experiment
chosen
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.
-
B.
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.
-
C.
Gurdon experiment
The Gurdon experiment was a landmark 1960s study in developmental biology demonstrating that the nucleus of a differentiated frog cell retains the full genetic information needed to direct the development of an entire organism, thereby proving the principle of nuclear equivalence and cellular reprogramming.
-
D.
bacteriophage T2
Bacteriophage T2 is a virus that infects Escherichia coli and was pivotal in experiments demonstrating that DNA is the genetic material.
-
E.
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.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
