List-I (Scientists)
A. Griffith
B. Avery, MacLeod and McCarty
C. Hershey and Chase
D. Meselson and Stahl
List-II (Finding)
I. Radioactive phosphorus and sulfur in bacteriophages showed that DNA enters the bacteria
II. Heavy nitrogen and a CsCl density gradient showed that DNA replicates semiconservatively
III. Heat-killed S strain bacteria transformed live R strain bacteria into a virulent form
IV. DNA alone from S bacteria transformed R bacteria, and DNase stopped the transformationIn the Hershey and Chase experiment, bacteriophages grown on a medium with radioactive sulfur were allowed to infect *E. coli*. The cells were then agitated in a blender and spun in a centrifuge. Which result was obtained, and why? →
