George W. Beadle
George Wells Beadle (October 22, 1903 – June 9, 1989) was an American geneticist. In 1958 he shared one-half of the Nobel Prize in Physiology or Medicine with Edward Tatum for their discovery of the role of genes in regulating biochemical events within cells. He also served as the 7th President of the University of Chicago. Beadle and Tatum's key experiments involved exposing the bread mold ''Neurospora crassa'' to x-rays, causing mutations. In a series of experiments, they showed that these mutations caused changes in specific enzymes involved in metabolic pathways. These experiments led them to propose a direct link between genes and enzymatic reactions, known as the One gene-one enzyme hypothesis. Education and early life George Wells Beadle was born in Wahoo, Nebraska. He was the son of Chauncey Elmer Beadle and Hattie Albro, who owned and operated a farm nearby. George was educated at the Wahoo High School and might himself have become a farmer if one of his teachers a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Robert Metzenberg
Robert Lee Metzenberg (June 11, 1930 – July 15, 2007) was an American geneticist known for his work on genetic regulation and metabolism with Neurospora crassa. Education and early life Robert Lee Metzenberg was born in Chicago, Illinois, USA. In 1951 Metzenberg graduated from Pomona College in California where he had specialised in chemistry with physics and biology as minor subjects. He then studied at the California Institute of Technology and was awarded a Ph.D. in 1955. 1951 and 1955, he earned a PhD at California Institute of Technology in the Division of Biological Sciences supervised by Herschel K. Mitchell. During this time he met and was influenced by several geneticists including George Beadle, Alfred Sturtevant, Herschel K. Mitchell and Max Delbrück. Career In 1955 Metzenberg was appointed as a professor at the University of Wisconsin where he remained until he retired in 1996. In 1977 he was appointed the John Bascom Professor by the U ...

Edward Tatum
Edward Lawrie Tatum (December 14, 1909 – November 5, 1975) was an American geneticist. He shared half of the Nobel Prize in Physiology or Medicine in 1958 with George Beadle for showing that genes control individual steps in metabolism. The other half of that year's award went to Joshua Lederberg. Beadle and Tatum's key experiments involved exposing the bread mold ''Neurospora crassa'' to x-rays, causing mutations. In a series of experiments, they showed that these mutations caused changes in specific enzymes involved in metabolic pathways. These experiments, published in 1941, led them to propose a direct link between genes and enzymatic reactions, known as the "one gene, one enzyme" hypothesis. Tatum went on to study genetics in bacteria. An active area of research in his laboratory was to understand the basis of Tryptophan biosynthesis in ''Escherichia coli''. Later, Tatum and his student Joshua Lederberg showed that ''E. coli'' could share genetic information through r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thomas Hunt Morgan Medal
The Thomas Hunt Morgan Medal is awarded by the Genetics Society of America (GSA) for lifetime contributions to the field of genetics. The medal is named after Thomas Hunt Morgan, the 1933 Nobel Prize winner, who received this award for his work with Drosophila and his "discoveries concerning the role played by the chromosome in heredity." Morgan recognized that Drosophila, which could be bred quickly and inexpensively, had large quantities of offspring and a short life cycle, would make an excellent organism for genetic studies. His studies of the white-eye mutation and discovery of sex-linked inheritance provided the first experimental evidence that chromosomes are the carriers of genetic information. Subsequent studies in his laboratory led to the discovery of recombination and the first genetic maps. In 1981 the GSA established the Thomas Hunt Morgan Medal for lifetime achievement to honor this classical geneticist who was among those who laid the foundation for modern genetic ...

Nobel Prize In Physiology Or Medicine
The Nobel Prize in Physiology or Medicine is awarded yearly by the Nobel Assembly at the Karolinska Institute for outstanding discoveries in physiology or medicine. The Nobel Prize is not a single prize, but five separate prizes that, according to Alfred Nobel's 1895 will, are awarded "to those who, during the preceding year, have conferred the greatest benefit to humankind". Nobel Prizes are awarded in the fields of Physics, Chemistry, Physiology or Medicine, Literature, and Peace. The Nobel Prize is presented annually on the anniversary of Alfred Nobel's death, 10 December. As of 2022, 114 Nobel Prizes in Physiology or Medicine have been awarded to 226 laureates, 214 men and 12 women. The first one was awarded in 1901 to the German physiologist, Emil von Behring, for his work on serum therapy and the development of a vaccine against diphtheria Diphtheria is an infection caused by the bacterium '' Corynebacterium diphtheriae''.

Gene
In biology, the word gene (from , ; "... Wilhelm Johannsen coined the word gene to describe the Mendelian units of heredity..." meaning ''generation'' or ''birth'' or ''gender'') can have several different meanings. The Mendelian gene is a basic unit of heredity and the molecular gene is a sequence of nucleotides in DNA that is transcribed to produce a functional RNA. There are two types of molecular genes: protein-coding genes and noncoding genes. During gene expression, the DNA is first copied into RNA. The RNA can be directly functional or be the intermediate template for a protein that performs a function. The transmission of genes to an organism's offspring is the basis of the inheritance of phenotypic traits. These genes make up different DNA sequences called genotypes. Genotypes along with environmental and developmental factors determine what the phenotypes will be. Most biological traits are under the influence of polygenes (many different genes) as well as ...

One Gene-one Enzyme Hypothesis
1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clement Markert
Clement Lawrence Markert (April 11, 1917 – October 1, 1999) was an American biologist credited with the discovery of isozymes (different forms of enzymes that catalyze the same reaction). He was a member of the National Academy of Sciences and American Academy of Arts and Sciences, and served as president of several biology societies. Markert was born in Las Animas, Colorado and raised in Pueblo, Colorado. He attended the University of Colorado, and in 1937, left college to fight in the Spanish Civil War—stowing away aboard a freighter to circumvent government travel restrictions. After returning to college, Markert completed his bachelor's degree in 1940; upon graduation, he married Margaret Rempfer, and they moved to UCLA for graduate work. He enrolled in the United States Merchant Marine to take part in World War II; by 1954 they had three children. After the war, he finished a master's degree at UCLA followed by a Ph.D. from Johns Hopkins University in 1948. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
