contained oxygen-requiring bacteria. He
then shone a light through a prism just

Hershey and Chase allowed
bacteriophage to grow on bacteria that
35
had been reared in the presence of S
32
and P. [Remember that protein
contains sulfur and nucleic acid contains
phosphorous.] The progeny
bacteriophage were then allowed to infect
bacteria that had been grown on normal
media. After an incubation time sufficient
for the bacteriophage to infect their hosts,
the "ghosts" were sheared off the surface
of the bacteria. When the "ghosts" were
separated from the bacteria by
35
centrifugation, the S was found with the
"ghosts" but not the bacteria. Conversely,
32
the P was found with the bacteria but
not the "ghosts". Based upon these and

the following conclusion.
