3 Identification card

4 field :bacteriologist and geneticist.
Alfred Day Hershey was born on December 4th, 1908, in Owosso, Michigan. He studied at the Michigan State College, where he obtained B.S. in 1930, and Ph.D. in In 1967 he got an honorary D.Sc. at the University of Chicago. field :bacteriologist and geneticist. awarded the Nobel Prize in Physiology or Medicine in 1969, Alfred D. Hershey died on May 22, 1997.

5 Martha Cowles Chase (1927 – August 8, 2003) She was 75.
Chase was only in her 20s when she worked with biologist Alfred D. Hershey on the "blender experiments" at the Cold Spring Harbor Laboratory in New York. Chase received her bachelor's degree in biology from the College of Wooster in Ohio, and her post-doctoral degree at the University of Southern California. her scientific career ended when she experienced suffering from dementia

6 When Hershey moved to Cold Spring Harbor, New York, in 1950 Department of Genetics, where he performed the famous Hershey-Chase blender experiment with Martha Chase

7 Evidence that viral can program cells

8 Bacteriophages (phages)
Bacteriophages (phages) are viruses that infect bacteria. Which of the viral component DNA-protein??

9 Experiment

11 Hershey and chase conclusion
Hershey and chase concluded that the DNA of the virus is injected in the host cell during infection, leaving the protein outside . The injected DNA provides genetic information that make the cell produce new viral DNA and protein to make new viruses
