-
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.
bacteriophage T2
Bacteriophage T2 is a virus that infects Escherichia coli and was pivotal in experiments demonstrating that DNA is the genetic material.
-
D.
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.
-
E.
Oswald Avery
Oswald Avery was a Canadian-American physician and molecular biologist best known for demonstrating that DNA is the material responsible for heredity.
