In an important experiment, a radioactively labeled bacteriophage was allowed to infect bacteria. In a first trial, the phage contained radioactive DNA, and radioactivity was detected inside the bacteria. Next, phage containing radioactive protein was used, and the radioactivity was not detected inside the bacteria. These experiments led to the conclusion that:. A) DNA is made of nucleotides.
B) genes carry information for making proteins.
C) the genes of this phage were made of DNA.
D) bacteriophages can infect bacteria.
