Extractions: in full ALFRED DAY HERSHEY (b. Dec. 4, 1908, Lansing, Mich., U.S.d. May 22, 1997, Syosset, N.Y.), American biologist who, along with and Salvador Luria , won the Nobel Prize for Physiology or Medicine in 1969. The prize was given for research done on bacteriophages (viruses that infect bacteria). Hershey earned a doctorate in chemistry from Michigan State College (now Michigan State University) in 1934 and then took a position at Washington University School of Medicine in St. Louis, Mo. He joined the staff of the Genetics Research Unit of the Carnegie Institution of Washington in 1950 after giving up his position as professor at Washington University. In 1963 he became director of the Genetics Research Unit. i.e., Hershey is most noted for the so-called blender experiment that he performed with Martha Chase in 1952. By showing that phage DNA is the principal component entering the host cell during infection, Hershey proved that DNA, rather than protein, is the genetic material of the phage.

Experiments That Inspire d Herelle was hopeful that this discovery would be useful in fighting disease In 1952, American biologists alfred hershey and Martha Chase set out to determine http://www.accessexcellence.org/AB/BC/Experiments_that_Inspire.html
Extractions: Chris Evers One of the greatest threats to human health is viral infection. Diseases caused by viruses range from the merely inconvenient (warts, the common cold), to the worrisome (flu, mumps, and measles), to the potentially fatal (hepatitis, polio, and AIDS). Humans are not alone in this suffering - all cellular organisms, even bacteria, can be attacked by viruses. The first bacterial viruses were discovered in 1917 by scientists working independently in London and Paris. The French scientist, Felix d'Herelle, was studying the feces of patients who had recovered from a bacterial dysentery. This somewhat unpleasant work led him to the discovery of an organism capable of killing bacteria - so small it could pass through a filter. He coined the term "bacteriophage," meaning eater of bacteria, to describe his discovery. d'Herelle was hopeful that this discovery would be useful in fighting disease. It was - in ways he never anticipated: The study of a bacterial virus turned out to be crucial in establishing the identity of DNA as the genetic material of all living things. In 1952, American biologists Alfred Hershey and Martha Chase set out to determine what composed the genetic material of a bacteriophage. They knew that a bacterial virus was an extremely simple organism, composed only of protein and DNA. The protein makes up the exterior of the virus, and the DNA is contained within it. When a bacterium is infected by a bacteriophage, the bacterium's internal machinery falls under the control of the virus, which uses the bacterium to produce more viruses. What Hershey and Chase wanted to know was: Which substance directed this takeover - DNA or protein?

Extractions: Provide students with a list of historical scientists/biologists based on available resources/references. I have provided a generalized list that covers a range of topics and time periods at the end of the activity. Indicate scientists on the list that you consider first priority with a star * and have students pick one * name and one non -starred name for the cards. Require that a * name be first choice for the biography scrapbooks. Students must complete basic research on their scientists using a minimum of three sources with a bibliography. If you have access to the Internet, here are some great URLS for science biographies: HSTM-Biographical Dictionary 4000 Years of Women in Science The Faces of Science - Afro-Americans in Science The time required to complete these projects will vary depending on whether you use class-time for research and work-time or assign the work outside of class. I generally include these projects while other material is being covered and have checkpoints and workdays in class along the way. Allowing some work time in class is often synergistic for student creativity. I also include time for presentation of the projects. Students need to appreciate the humanity of the people involved in doing science. Unfortunately straightforward biography reports can be fairly boring. Here are two biologist biography projects that call for more creative approaches on the part of students. The Famous Biologist Cards project is shorter and can involve group and class interactions. The Biography Scrapbook is an individualized and lengthier project .

Franklin W. Stahl (ed.). xii + 359 pp. Cold Spring Harbor Laboratory Press, 2000. $39. The focus in molecular biology in the 1950s was on whether DNA, protein or some combination of the two was the heritable material passed between cells. The work of Alfred D. Hershey, Max Delbr?ck and Salvador E. Luria answered this question and led to their sharing the Nobel Prize for Physiology or Medicine in 1969. In We Can Sleep Later

Extractions: HERSHEY - CHASE Il dubbio su quale molecola, proteine o DNA, dovesse essere il portatore dell'informazione permase anche dopo i risultati raggiunti da Avery . Il dilemma su quale delle due componenti dei fagi contenesse i geni virali, cioè il materiale ereditario che dirige la sintesi di nuovi virus all'interno della cellula batterica, fu risolta nel 1952 da Alfred D. Hershey e da Martha Chase. Grazie ai loro esperimenti sui fagi, è stato possibile dimostrare che solamente il DNA dei batteriofagi era coinvolto nel processo di moltiplicazione dei fagi.
