Which of the following statements best describes a result and conclusion of the experiment by Alfred Hershey and Martha Chase conducted in 1952 , in which they infected bacteria with T2 bacteriophages ('phages')?
a.
Based on their experiment, Hershey and Chase concluded that DNA is the genetic material of T2 phages because the supernatant was radioactive when they used a batch of T2 phages that had been grown with radioactive sulfur.
b.
Based on their experiment, Hershey and Chase concluded that protein is not the genetic material of T2 phages because the pellet was not radioactive when they used a batch of 12 phages that had been grown with radioactive phosphorous.
c.
Based on their experiment, Hershey and Chase concluded that DNA is the genetic material of T2 phages because the pellet was radioactive when they used a batch of T2 phages that had been grown with radioactive phosphorous.
d.
Based on their experiment, Hershey and Chase concluded that protein is not the genetic material of T2 phages because the pellet was radioactive when they used a batch of T2 phages that had been grown with radioactive phosphorous.
