Ananda Mohan Chakrabarty
Ananda Mohan Chakrabarty ( bn, আনন্দমোহন চক্রবর্তী ''Ānandamōhan Cakrabartī''), PhD (4 April 1938 – 10 Jul 2020) was an Indian American microbiologist, scientist, and researcher, most notable for his work in directed evolution and his role in developing a genetically engineered organism using plasmid transfer while working at GE, the patent for which led to landmark Supreme Court case, ''Diamond v. Chakrabarty''. Early life Ananda (generally called "Al" by scientific colleagues) Chakrabarty was born in Sainthia on 4 April 1938. He attended Sainthia High School, Ramakrishna Mission Vidyamandira and St. Xavier's College, Calcutta—in that order—during the course of his undergraduate education. Prof. Chakrabarty received his PhD. from the University of Calcutta in Kolkata, West Bengal in 1965. Scientific work Prof. Chakrabarty genetically engineered a new species of ''Pseudomonas'' bacteria ("the oil-eating bacteria") in 1971 wh ...

Sainthia
Sainthia (formerly Nandipur) is a city and a municipality in Suri Sadar subdivision of Birbhum district in the Indian state of West Bengal. The city is known as business city of Birbhum district. The city is under the jurisdiction of Sainthia police station. Sainthia is the fourth most populous city in Birbhum district and 95th most populous city in West Bengal. The city covers an area of 10 km2 and had a population of 44,601 in 2011. Located on the banks of Mayurakshi River, Sainthia has been a major human settlement. The city is famous for Nandikeshwari Temple, one of the Shakti Peethas in Indian subcontinent. Etymology It is believed that the name ''Sainthia'' is derived from 'Saaita', a term used in 'Khero Khata' (Business Book) by the merchants of Sainthia after worshiping Goddess Nandikeshwari in Poila Boishakh and Vijaya Dashami. Nandipur was the ancient name of Sainthia. The name Nandipur was originated from the famous temple of Nandikeshwari. The word Nandi comes ...

Bacteria
Bacteria (; singular: bacterium) are ubiquitous, mostly free-living organisms often consisting of one biological cell. They constitute a large domain of prokaryotic microorganisms. Typically a few micrometres in length, bacteria were among the first life forms to appear on Earth, and are present in most of its habitats. Bacteria inhabit soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria are vital in many stages of the nutrient cycle by recycling nutrients such as the fixation of nitrogen from the atmosphere. The nutrient cycle includes the decomposition of dead bodies; bacteria are responsible for the putrefaction stage in this process. In the biological communities surrounding hydrothermal vents and cold seeps, extremophile bacteria provide the nutrients needed to sustain life by converting dissolved compounds, such as hydrogen sulphide and methane, to energy. Bacteria also live in symbiotic and parasitic relationsh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

United States Court Of Customs And Patent Appeals
The United States Court of Customs and Patent Appeals (CCPA) was a United States federal court which existed from 1909 to 1982 and had jurisdiction over certain types of civil disputes. History The CCPA began as the United States Court of Customs Appeals, created by the Payne–Aldrich Tariff Act of August 5, 1909, and it started its work the following year, on April 22, 1910. Five judges for the new court were appointed by President Taft: Robert Morris Montgomery, William H. Hunt, James Francis Smith, Orion M. Barber and Marion De Vries. The jurisdiction was originally appeals from decisions of the Board of General Appraisers, and no further appellate review was permitted. This changed in 1914, when writ of certiorari by the United States Supreme Court was allowed. The Patent Act of 1922 enlarged the jurisdiction of the court to include appeals on questions of law from Tariff Commission findings in proceedings relating to unfair practices in the import trade. In 1929 the court' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Genetically Modified Organism
A genetically modified organism (GMO) is any organism whose genetic material has been altered using genetic engineering techniques. The exact definition of a genetically modified organism and what constitutes genetic engineering varies, with the most common being an organism altered in a way that "does not occur naturally by mating and/or natural recombination". A wide variety of organisms have been genetically modified (GM), from animals to plants and microorganisms. Genes have been transferred within the same species, across species (creating transgenic organisms), and even across kingdoms. New genes can be introduced, or endogenous genes can be enhanced, altered, or knocked out. Creating a genetically modified organism is a multi-step process. Genetic engineers must isolate the gene they wish to insert into the host organism and combine it with other genetic elements, including a promoter and terminator region and often a selectable marker. A number of techniques are a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private law and the patent holder mus ...

Pseudomonas Putida
''Pseudomonas putida'' is a Gram-negative, rod-shaped, saprotrophic soil bacterium. Based on 16S rRNA analysis, ''P. putida'' was taxonomically confirmed to be a ''Pseudomonas'' species (''sensu stricto'') and placed, along with several other species, in the ''P. putida'' group, to which it lends its name. However, phylogenomic analysis of complete genomes from the entire ''Pseudomonas'' genus clearly showed that the genomes that were named as ''P. putida'' did not form a monophyletic clade, but were dispersed and formed a wider evolutionary group (the putida group) that included other species as well, such as ''P. alkylphenolia, P. alloputida, P. monteilii, P. cremoricolorata, P. fulva, P. parafulva, P. entomophila, P. mosselii, P. plecoglossicida'' and several genomic species (new species which are currentely not validely defined as new species. A variety of ''P. putida'', called multiplasmid hydrocarbon-degrading ''Pseudomonas'', is the first patented organism in th ...

UV Light
Ultraviolet (UV) is a form of electromagnetic radiation with wavelength from 10 nm (with a corresponding frequency around 30 PHz) to 400 nm (750 THz), shorter than that of visible light, but longer than X-rays. UV radiation is present in sunlight, and constitutes about 10% of the total electromagnetic radiation output from the Sun. It is also produced by electric arcs and specialized lights, such as mercury-vapor lamps, tanning lamps, and black lights. Although long-wavelength ultraviolet is not considered an ionizing radiation because its photons lack the energy to ionize atoms, it can cause chemical reactions and causes many substances to glow or fluoresce. Consequently, the chemical and biological effects of UV are greater than simple heating effects, and many practical applications of UV radiation derive from its interactions with organic molecules. Short-wave ultraviolet light damages DNA and sterilizes surfaces with which it comes into contact. For huma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plasmids
A plasmid is a small, extrachromosomal DNA molecule within a cell that is physically separated from chromosomal DNA and can replicate independently. They are most commonly found as small circular, double-stranded DNA molecules in bacteria; however, plasmids are sometimes present in archaea and eukaryotic organisms. In nature, plasmids often carry genes that benefit the survival of the organism and confer selective advantage such as antibiotic resistance. While chromosomes are large and contain all the essential genetic information for living under normal conditions, plasmids are usually very small and contain only additional genes that may be useful in certain situations or conditions. Artificial plasmids are widely used as vectors in molecular cloning, serving to drive the replication of recombinant DNA sequences within host organisms. In the laboratory, plasmids may be introduced into a cell via transformation. Synthetic plasmids are available for procurement over the intern ...

Genes
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 gen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crude Oil
Petroleum, also known as crude oil, or simply oil, is a naturally occurring yellowish-black liquid mixture of mainly hydrocarbons, and is found in geological formations. The name ''petroleum'' covers both naturally occurring unprocessed crude oil and petroleum products that consist of refined crude oil. A fossil fuel, petroleum is formed when large quantities of dead organisms, mostly zooplankton and algae, are buried underneath sedimentary rock and subjected to both prolonged heat and pressure. Petroleum is primarily recovered by oil drilling. Drilling is carried out after studies of structural geology, sedimentary basin analysis, and reservoir characterisation. Recent developments in technologies have also led to exploitation of other Unconventional (oil & gas) reservoir, unconventional reserves such as oil sands and oil shale. Once extracted, oil is refined and separated, most easily by Continuous distillation#Continuous distillation of crude oil, distillation, into innume ...
