Background image of page 2
3 Sample Question (Lecture 1) 19. A new type of bacteriophage contains RNA as the genetic material instead of DNA. Mrs. McDonald performs a Hershey-Chase experiment using this new bacteriophage. She labels the phage RNA with 32 P and the protein with 35 S. These doubly-labeled phage are used to infect bacteria and then the mix is placed into the blender so that the phage heads are separated from the infected cells. The infected cells are isolated and the radioactivity in these cells counted. Which type(s) of radioactive species are observed? (A) 32 P only (B) 35 S only (C) 32 P and 35 S (D) 14 N only (E) No radioactivity is observed
