Extractions: A developmental mutation detected by its strong effect on neoplasia is the Multiple intestinal neoplasia ( Min ) allele of the murine Apc gene ( adenomatous polyposis coli ). A network of genes impinging on its neoplastic phenotypes is being discovered. One modifier locus, , confers tumor resistance by encoding a locally active secretory phospholipase. A second modifier locus, Dnmt , seems to control by DNA methylation the activity of a negative regulator of tumor growth. The range of action of modifying genes and their effects on the clonal structure of intestinal tumors are being studied in chimeric mice. Thliveris, A. T., Halberg, R. B., Clipson, L., Dove, W.

Extractions: Alfred Day Hershey, Ph.D., a Nobel laureate who spent the first 16 years of his career at the School of Medicine, died Thursday, May 22, 1997, at his home in Syosset, N.Y. He was 88. Hershey joined the Washington University Department of Bacteriology and Immunology in 1934 after receiving a doctorate in chemistry from Michigan State College. Inspired by department head Jacques J. Bronfenbrenner, he began to work with bacteriophages viruses that infect bacterial cells. At a time when few people were studying the chemical or genetic properties of viruses, Hershey developed ways to recognize and analyze viral genetic traits, believing that studies with such a simple form of life might reveal basic hereditary principles. In 1946, he produced the first convincing evidence that two strains of a virus can exchange genetic material if they infect the same bacterial cell. Hershey moved to the Genetics Research Unit of the Carnegie Institution at Cold Spring Harbor Laboratory in New York in 1950. Two years later, he and geneticist Martha Chase discovered how bacterial viruses infect cells and provided a critical piece of evidence for the view that DNA, not protein, was the genetic material. They labeled the protein coat of one batch of phages with radioactive sulfur and the DNA core of another batch with radioactive phosphorus. Tracking the labels during infection, they observed that most of the protein label stayed outside the bacterial cell and could be removed with a blender, whereas the DNA label entered the bacterium and reappeared in progeny phage. This experiment proved that genetic information is in DNA, not protein, as some researchers had proposed.

Extractions: The Biology Web (Home) General Biology 1 General Biology 2 Human Biology DNA Miescher isolated the nuclei of white blood cells obtained from pus cells. His experiments revealed that nuclei contained a chemical that contained nitrogen and phosphorus but no sulfur. He called the chemical nuclein because it came from nuclei. It later became known as nucleic acid. Garrod noticed that people with certain genetic abnormalities (inborn errors of metabolism) lacked certain enzymes. This observation linked proteins (enzymes) to genetic traits. When Streptococcus pneumoniae (pneumococcus) bacteria are grown on a culture plate, some produce smooth shiny colonies (S) while others produce rough colonies (R). This is because the S strain bacteria have a mucous (polysaccharide) coat, while R strain does not. Mice infected with the S strain die from pneumonia infection but mice infected with the R strain do not develop pneumonia.

Extractions: Dr. Alfred Day Hershey Alfred Day Hershey was born Dember 4, 1908 at 515 E. Mason St. Owosso, MI, to Robert D. and Alma (Wilber) Hershey. He graduated from Owosso High School in about 1925 and later graduated from Michigan State University was a B.S. in Science in 1930 and a Ph.D. in 1934. In 1967 he got an honorary D.Sc. at the University of Chicago. From 1934 till 1950 he was engaged in teaching and research, at the Department of Bacteriology, Washington University School of Medicine. In 1950 he became a Staff Member, at the Department of Genetics, Carnegie Institution of Washington, Cold Spring Harbor, New York; in 1962 he was appointed Director of the Genetics Research Unit of the same institution. Alfred Hershey married Harriet Davidson in 1945, they have one son, Peter. While researching bacteriophages (viruses which infect bacteria) at Washington University (St Louis) (1934-50), he eventually, in 1943, joined the informal âphage groupâ forum begun by Max Delbruck and Salvador Luria. Hershey moved to the Carnegie Institution's laboratory in Cold Spring Harbor, NY (1950-74). Together with geneticist Martha Chase, he discovered (1952) that bacteriophage DNA alters genetic replication of the host bacterium, thus proving that DNA is the genetic material of the virus.
