  1. #8Hershey and Chase Experiment Zabrina Shvartsman Ashley Sroka Brendan Weiss

  2. EXPERIMENT • They wanted to see if PROTEIN or DNA was responsible for hereditary action

  3. EXPERIMENT CON’T. • Meaning, they wanted to know if you inherited your hair and eye color from your parents because of the PROTEIN or the DNA

  4. EXPERIMENT CON’T. • They used bacteriophages (viruses that invade bacteria) to discover the solution

  5. EXPERIMENT CON’T. • PROTEINS injected with sulfur • When they replicated, the new bacteriophages weren’t radioactive • PROTEINS are not responsible for hereditary action

  6. EXPERIMENT CON’T. • DNA injected with phosphorous • When they replicated, the new bacteriophages were radioactive • DNA is responsible for hereditary action

  7. EXPERIMENT CON’T. • http://nortonbooks.com/college/biology/animations/ch12a02.htm

  8. Question # 8 • You want to use a radioactive tracer that will label only the protein in an RNA virus. Assume the virus is composed of only a protein coat and an RNA core. Which of the following would you use? • Radioactive phosphorous • Radioactive nitrogen • Radioactive sulfur • Radioactive carbon

  9. Question # 8 con’t. • You would use sulfur • Proteins contain sulfur, and not phosphorous • When the Hershey-Chase experiment tested the proteins for hereditary action, their replicates were not radioactive
