In one part of their experiment, Hershey and chase used radioactive phosphorus to label DNA in their T2 bacteriophages. what conclusion did they come to as a result?
A. they found radioactive phosphorus in the liquid medium, leading them to believe that DNA was not the genetic material.
B. they found radioactive phosphorus in the bacteria, leading them to believe that DNA was the genetic material.
C. radioactive phosphorus did not transfer into the bacteria, leading them to continue their investigations with radioactive sulfur.

Answer:B

Explanation:

Alfred Hershey and Martha Chase in 1952 conducted an experiment to prove that the DNA was actually the carrier for hereditary material. Prior to that time,most scientist beloved that the DNA was just an inert molecule and that proteins carried the genetic information. In the experiment,In their experiments, Hershey and Chase showed that when bacteriophages, which are composed of DNA and protein, infect bacteria, their DNA enters the host bacterial cell, but most of their protein does not. Hershey and Chase and subsequent discoveries all served to prove that DNA is the hereditary material.
