Robert Horvitz
Howard Robert Horvitz ForMemRS NAS AAA&S APS NAM (born May 8, 1947) is an American biologist best known for his research on the nematode worm ''Caenorhabditis elegans'', for which he was awarded the 2002 Nobel Prize in Physiology or Medicine, together with Sydney Brenner and John E. Sulston, whose "seminal discoveries concerning the genetic regulation of organ development and programmed cell death" were "important for medical research and have shed new light on the pathogenesis of many diseases". Education and early life Horvitz was born in Chicago, Illinois to Jewish parents, the son of Mary R. (Savit), a school teacher, and Oscar Freedom Horvitz, a GAO accountant. He majored in mathematics at Massachusetts Institute of Technology, where he joined Alpha Epsilon Pi and spent his summers working for IBM, at first wiring panels for accounting machines and then in his final summer helping to develop IBM's Conversational Programming System. During his senior year, Horvitz took his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

RNA Polymerase
In molecular biology, RNA polymerase (abbreviated RNAP or RNApol), or more specifically DNA-directed/dependent RNA polymerase (DdRP), is an enzyme that synthesizes RNA from a DNA template. Using the enzyme helicase, RNAP locally opens the double-stranded DNA so that one strand of the exposed nucleotides can be used as a template for the synthesis of RNA, a process called transcription. A transcription factor and its associated transcription mediator complex must be attached to a DNA binding site called a promoter region before RNAP can initiate the DNA unwinding at that position. RNAP not only initiates RNA transcription, it also guides the nucleotides into position, facilitates attachment and elongation, has intrinsic proofreading and replacement capabilities, and termination recognition capability. In eukaryotes, RNAP can build chains as long as 2.4 million nucleotides. RNAP produces RNA that, functionally, is either for protein coding, i.e. messenger RNA (mRNA); or n ...

Enterobacteria Phage T4
Escherichia virus T4 is a species of bacteriophages that infect ''Escherichia coli'' bacteria. It is a double-stranded DNA virus in the subfamily '' Tevenvirinae'' from the family Myoviridae. T4 is capable of undergoing only a lytic lifecycle and not the lysogenic lifecycle. The species was formerly named T-even bacteriophage, a name which also encompasses, among other strains (or isolates), Enterobacteria phage T2, Enterobacteria phage T4 and Enterobacteria phage T6. Use in research Dating back to the 1940s and continuing today, T-even phages are considered the best studied model organisms. Model organisms are usually required to be simple with as few as five genes. Yet, T-even phages are in fact among the largest and highest complexity virus, in which these phage's genetic information is made up of around 300 genes. Coincident with their complexity, T-even viruses were found to have the unusual base hydroxymethylcytosine (HMC) in place of the nucleic acid base cytosine. ...

Conversational Programming System
Conversational Programming System or CPS was an early Time-sharing system offered by IBM which ran on System/360 mainframes ''circa'' 1967 through 1972 in a partition of OS/360 Release 17 MFT II or MVT or above. CPS was implemented as an interpreter, and users could select either a rudimentary form of BASIC or a reasonably complete version of PL/I. A third option provided remote job entry (RJE) features allowing users to submit JCL job streams for batch processing. A fourth option was called control mode. Normally, only the system operator would be permitted to use control mode. The available features in control mode included: *Send a message to an individual user or all users. *Clobber (today it would be called re-boot) a specific user's virtual CPS machine. *Monitor the activity of an individual user. *Terminate the entire CPS system. CPS provided a highly interactive user experience. It accomplished this by giving an immediate syntax error (when necessary) as soon as ...

Alpha Epsilon Pi
Alpha Epsilon Pi (), commonly known as AEPi, is a college fraternity founded at New York University in 1913 by Charles C. Moskowitz and ten other men. The fraternity has more than 150 active chapters across the United States, Canada, United Kingdom, and Israel, and has initiated more than 110,000 members. Although the fraternity is based upon Jewish principles, it is non-discriminatory and is open to all who are willing to espouse its purpose and values. History Alpha Epsilon Pi was founded in 1913 under the Washington Square Arch at New York University (NYU) by Charles C. Moskowitz and 10 other Jewish men: David K. Schafer, Isador M. Glazer, Herman L. Kraus, Arthur E. Leopold, Benjamin M. Meyer, Arthur M. Lipkint, Charles J. Pintel, Maurice Plager, Hyman Shulman, and Emil J. Lustgarten. These men are known as the "Immortal 11."

Caenorhabditis Elegans
''Caenorhabditis elegans'' () is a free-living transparent nematode about 1 mm in length that lives in temperate soil environments. It is the type species of its genus. The name is a blend of the Greek ''caeno-'' (recent), ''rhabditis'' (rod-like) and Latin ''elegans'' (elegant). In 1900, Maupas initially named it '' Rhabditides elegans.'' Osche placed it in the subgenus ''Caenorhabditis'' in 1952, and in 1955, Dougherty raised ''Caenorhabditis'' to the status of genus. ''C. elegans'' is an unsegmented pseudocoelomate and lacks respiratory or circulatory systems. Most of these nematodes are hermaphrodites and a few are males. Males have specialised tails for mating that include spicules. In 1963, Sydney Brenner proposed research into ''C. elegans,'' primarily in the area of neuronal development. In 1974, he began research into the molecular and developmental biology of ''C. elegans'', which has since been extensively used as a model organism. It was the first multicellu ...

Nematode
The nematodes ( or grc-gre, Νηματώδη; la, Nematoda) or roundworms constitute the phylum Nematoda (also called Nemathelminthes), with plant-Parasitism, parasitic nematodes also known as eelworms. They are a diverse animal phylum inhabiting a broad range of environments. Less formally, they are categorized as Helminths, but are taxonomically classified along with Arthropod, arthropods, Tardigrade, tardigrades and other moulting animalia, animals in the clade Ecdysozoa, and unlike platyhelminthe, flatworms, have tubular digestion, digestive systems with openings at both ends. Like tardigrades, they have a reduced number of Hox genes, but their sister phylum Nematomorpha has kept the ancestral protostome Hox genotype, which shows that the reduction has occurred within the nematode phylum. Nematode species can be difficult to distinguish from one another. Consequently, estimates of the number of nematode species described to date vary by author and may change rapidly over ...

Biologist
A biologist is a scientist who conducts research in biology. Biologists are interested in studying life on Earth, whether it is an individual cell, a multicellular organism, or a community of interacting populations. They usually specialize in a particular branch (e.g., molecular biology, zoology, and evolutionary biology) of biology and have a specific research focus (e.g., studying malaria or cancer). Biologists who are involved in basic research have the aim of advancing knowledge about the natural world. They conduct their research using the scientific method, which is an empirical method for testing hypotheses. Their discoveries may have applications for some specific purpose such as in biotechnology, which has the goal of developing medically useful products for humans. In modern times, most biologists have one or more academic degrees such as a bachelor's degree plus an advanced degree like a master's degree or a doctorate. Like other scientists, biologists can be fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
