Alfred Hershey
Alfred Day Hershey (December 4, 1908 – May 22, 1997) was an American Nobel Prize–winning bacteriologist and geneticist. He was born in Owosso, Michigan and received his B.S. in chemistry at Michigan State University in 1930 and his Ph.D. in bacteriology in 1934, taking a position shortly thereafter at the Department of Bacteriology at Washington University in St. Louis. He began performing experiments with bacteriophages with Italian-American Salvador Luria, German Max Delbrück, and observed that when two different strains of bacteriophage have infected the same bacteria, the two viruses may exchange genetic information. He moved with his research partner Martha Chase to Laurel Hollow, New York, in 1950 to join the Carnegie Institution of Washington's Department of Genetics, where he and Martha Chase performed the famous Hershey–Chase experiment in 1952. This experiment provided additional evidence that DNA, not protein, was the genetic material of life. Notable post-d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Owosso, Michigan
Owosso is the largest city in Shiawassee County in the U.S. state of Michigan. The population was 15,194 at the 2010 census. The city is mostly surrounded by Owosso Township on its west, but the two are administered autonomously. The city was named after Chief Wosso, an Ojibwe leader of the Shiawassee area. History Alfred L. and Benjamin O. Williams were early European-American settlers in the area. They were joined by Elias Comstock, who built the first permanent home in the settlement. Dr. John B. Barnes, a physician and a judge, and Sophronia King Barnes moved to Owosso in 1842. They lived on Oliver and Water streets where they operated an Underground Railroad waystation, where they provided aid and shelter for enslaved African Americans. Owosso was incorporated as a city in 1859, at which time it had 1000 people. The city's first mayor was Amos Gould, a judge originally from New York. Many other settlers also migrated across the Northern Tier from New York and New E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Martha Chase
Martha Cowles Chase (November 30, 1927 – August 8, 2003), also known as Martha C. Epstein, was an American geneticist who in 1952, with Alfred Hershey, experimentally helped to confirm that DNA rather than protein is the genetic material of life. Early life and college education Chase was born in 1927 in Cleveland, Ohio. Her father was a Western Reserve University Science Instructor and she grew up with her family in Cleveland Heights, Ohio. After graduating from Cleveland Heights High School, she received a bachelor's degree from the College of Wooster in 1950, then worked as a research assistant before returning to school in 1959 and receiving a PhD in Microbiology from the University of Southern California in 1964. Research and later life In 1950, Chase began working as a research assistant at Cold Spring Harbor Laboratory in the laboratory of bacteriologist and geneticist Alfred Hershey. In 1952, she and Hershey performed the Hershey–Chase experiment, which h ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Papal Infallibility
Papal infallibility is a dogma of the Catholic Church which states that, in virtue of the promise of Jesus to Peter, the Pope when he speaks '' ex cathedra'' is preserved from the possibility of error on doctrine "initially given to the apostolic Church and handed down in Scripture and tradition". It does not mean that the pope cannot sin or otherwise err in most situations. This doctrine, defined dogmatically at the First Vatican Council of 1869–1870 in the document '' Pastor aeternus'', is claimed to have existed in medieval theology and to have been the majority opinion at the time of the Counter-Reformation. The doctrine of infallibility relies on one of the cornerstones of Catholic dogma, that of papal supremacy, whereby the authority of the pope is the ruling agent as to what are accepted as formal beliefs in the Catholic Church. The use of this power is referred to as speaking ''ex cathedra''. "Any doctrine 'of faith or morals' issued by the pope in his capacity a ...

Franklin Stahl
Franklin (Frank) William Stahl (born October 8, 1929) is an American molecular biologist and geneticist. With Matthew Meselson, Stahl conducted the famous Meselson-Stahl experiment showing that DNA is replicated by a semiconservative mechanism, meaning that each strand of the DNA serves as a template for production of a new strand. He is Emeritus Professor of Biology at the University of Oregon's Institute of Molecular Biology in Eugene, Oregon. Career Stahl, like his two older sisters, graduated from the public schools of Needham, a Boston suburb. In 1951, he was awarded an AB degree in biology from Harvard College, and matriculated in the biology department of the University of Rochester. His interest in genetics was cemented in 1952 by his introduction to bacterial viruses (phages) in a course taught by A. H. (Gus) Doermann at the Cold Spring Harbor Biological Laboratory. In 1956, he received a PhD in biology for his work with Doermann on the genetics of T4 phage. In 1955 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Christians
Christians () are people who follow or adhere to Christianity, a monotheistic Abrahamic religion based on the life and teachings of Jesus Christ. The words '' Christ'' and ''Christian'' derive from the Koine Greek title ''Christós'' (Χριστός), a translation of the Biblical Hebrew term ''mashiach'' (מָשִׁיחַ) (usually rendered as ''messiah'' in English). While there are diverse interpretations of Christianity which sometimes conflict, they are united in believing that Jesus has a unique significance. The term ''Christian'' used as an adjective is descriptive of anything associated with Christianity or Christian churches, or in a proverbial sense "all that is noble, and good, and Christ-like." It does not have a meaning of 'of Christ' or 'related or pertaining to Christ'. According to a 2011 Pew Research Center survey, there were 2.2 billion Christians around the world in 2010, up from about 600 million in 1910. Today, about 37% of all Christians live in the ...

Viral Replication
Viral replication is the formation of biological viruses during the infection process in the target host cells. Viruses must first get into the cell before viral replication can occur. Through the generation of abundant copies of its genome and packaging these copies, the virus continues infecting new hosts. Replication between viruses is greatly varied and depends on the type of genes involved in them. Most DNA viruses assemble in the nucleus while most RNA viruses develop solely in cytoplasm. Viral production / replication Viruses multiply only in living cells. The host cell must provide the energy and synthetic machinery and the low- molecular-weight precursors for the synthesis of viral proteins and nucleic acids. The virus replication occurs in seven stages, namely; # Attachment # Entry, # Uncoating, # Transcription / mRNA production, # Synthesis of virus components, # Virion assembly and # Release (Liberation Stage). Attachment It is the first step of viral replicat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Anna Marie (Ann) Skalka (née Sturn) is an American virologist, molecular biologist and geneticist who is professor emeritus and senior advisor to the president at the Fox Chase Cancer Center. She is a co-author of a textbook on virology, ''Principles of Virology''.
