Genetic interactions - Genetic interactions Genetic interactions, in genetics, are interactions that occur between two or more mutations that results in a new phenotype. Studying genetic interactions can reveal gene function, the nature of the mutations, functional redundancy, and protein interactions. Because protein complexes are responsible for most biological functions, genetic interactions are a powerful tool. Examples of pair-wise interactions: Suppression - the double mutant is wild type Epistasis - the double mutant is like one of the single mutants Synthetic lethality - the double mutant is lethal Intragenic complementation - two mutations cause similar phenotypes and map to the same locus yet show complementation in heterozygotes. Unlinked non-complementation - two mutations fail to complement but do not map to the same locus.
Morphogenetic field - thing, as part of its epigenetics, and may also shape its behaviour and coordination with other beings, just as gravity, magnetism and quantum entanglement affect interactions between physical particles. Such fields are thought by some to provide a scientific explanation for the experience of telepathy, coincidence and serendipity, but experimental evidence of this is inconclusive - Sheldrake's own experiments are disputed, with some claiming that his results are statistically not significant. In A New Science of Life (1981, second edition 1985) and Presence of the Past: A Field Theory of Life (1988), his work on botany went public, and proved controversial. As he drifted away from interest in mainstream institutions, he later sought a list of Seven Experiments That Could Change The World, (1994) which included, among other things, the seed.
Endosymbiont - smallest of known bacterial genomes and have lost many genes that are commonly found in other bacteria. Presumably these genes are not needed in the environment of the host insect cell. (A complementary theory as to why the bacteria may have lost genes, Muller’s ratchet, is that since the endosymbionts are maternally transmitted and have no opportunity to exchange genes with other bacteria, it is more difficult to keep good genes in all individuals in a population of these endosymbionts.) Research in which a parallel phylogeny of bacteria and insects was inferred supports the belief that the obligate endosymbionts are transferred only vertically (i.e. from the mother), and not horizontally (i.e. by escaping the host and entering a new host). Attacking obligate bacterial endosymbionts may present a way to control their.
Biochemistry - Biochemistry Biochemistry is the study of the chemical reactions and interactions that take place in living organisms, especially the structure and function of their components, such as proteins, carbohydrates, lipids, nucleic acids, and other biomolecules present in cellss. Biochemistry could also (now) be defined as being the chemistry of enzyme-mediated reactions, whether in vivo or in the test tube, with natural or artificially modified enzymes and other chemicals. Development of biochemistry The dawn of biochemistry may have been the discovery of the first enzyme, diastase, in 1833 by Anselme Payen. In 1828, Friedrich Wöhler published a paper about the synthesis of urea, proving that organic compounds can be created artificially, in contrast to the common belief of the time that organic compounds can only be made by living organisms. Since then,.
Business Workflow Analysis / Business Management Systems p2p - conditions of life and work. BWA is a system network workflow peer to peer, a new conception of workflow which places human resources, costs that they generate and added value by learnings and experience in the centre of considerations and neither only the schedules, documents,freight,messaging or flux. Methodological bases of the business management systems p2p. The organization is a field of interactions, games of roles and objectives above ordered (objectives which can not be reached by the efforts of the only one). It is necessary so " to play collective " while strengthening the individual capacities. Performance, merit and motivation are inextricable of the economy of costs and the management of the performance. The costs of diagnosed dysfunctions are an active factor accessible to all the organizations which wish to improve.
Tunguska event - the asteroid through the atmosphere caused pressures and temperatures to build up to a point where the asteroid abruptly disintegrated in a huge explosion. The destruction would have had to be so complete that no remnants of substantial size survived, and the material scattered into the upper atmosphere during the explosion would have caused the skyglows. However, it remains an open question why the meteorite should have disintegrated so abruptly. Electromagnetic effect The Tunguska Event does appear to be similar to magnetic storms that occur after thermonuclear explosions (such as from a nuclear weapon) in the stratosphere. Anomalous concentrations of electrical energy in the region could have produced an explosive releases of energy. Electromagnetic fireballs, spherical plasmoidss, and ball lightning have been reported to exhibit the same phenonomena. Other plasma and.
Signal transduction - many ways: different kinds of molecules may buffet its surface, its body may be heated or cooled, it may be struck by light of various wavelengths, stretched, sheared or electrified (the nerves and muscles, for example). Signal transduction mediates how cells respond to such stimuli. Most stimuli impinge from the outside and interact with the cell membrane. Many "signalling molecules," such as the neurotransmitters that allow nerve cells to communicate across synapses, bind to receptor proteins in the membrane and open portals in it. Responses Responses triggered by signal transduction include the activation of a gene, the production of metabolic energy and cell locomotion, for example through remodelling of the cell skeleton. Gene activation leads to further effects, since genes are expressed as proteins, many of which are enzymes, transcription factors.
Social sciences - for human behavior directly. In Pascal's case the famous wager, for Leibniz, the invention of binary computation and for Kepler the intervention of angels to guide the planets. In the realm of other disciplines, this created a pressure to express ideas in the form of mathematical relationships. Such relationships, called "Laws" after the usage of the time, see Philosophy of Science, became the model which other disciplines would emmulate. August Comte (1797-1857) argued that ideas pass through three rising stages, Theological, Philosophical and Scientific. He defined the difference as the first being rooted in assumption, the second in critical thinking, and the third in positive observation. This framework, still rejected by many, encapsulates the thinking which was to push economic study from being a descriptive to a mathematically based discipline. Karl.
Penetrance - with which it has been associated. In some cases, the qualities in question will only occur when the gene is present; in other cases, they may occur for unrelated reasons. In the latter case, it will be more difficult to distinguish environmental from genetic factors, or even to detect that there is a genetic contribution at all. Penetrance and heritability appear closely related at first glance, but in fact it is possible to carry a huge number of inherited genes with low penetrance and not be aware of them. The opposite is not the case however, if you carry a higher penetrant gene, you will know. Most of the genes that are used as examples in genetics textbooks are highly penetrant, and the symptoms that they are associated with are highly.
Phage - viruses that infect eukaryotes, phages consist of an outer protein hull and the enclosed genetic material (which consists of double-stranded DNA in 95% of the phages known) of 5-650 kbp (kilo base pairs). Phages were discovered independently by Frederick Twort in 1915 and by Félix D’Herelle in 1917. Phages infect only specific bacteria. Some phages are virulent, meaning that upon infecting a cell they immediately begin reproducing, and within a short time lyse (destroy) the cell, releasing new phages. (A famous quote from the microbiologist Mark Müller says: Bacteria don't die, they just phage away.) Some phages (so-called temperate phages) can instead enter a relatively harmless state, either integrating their genetic material into the chromosomal DNA of the host bacterium (much like endogenous retroviruseses in animals) or establishing themselves as plasmids..
Protein - protein combining can be achieved over the longer period of the day. Ovo-lacto vegetarians usually do not have this problem, since egg's white and cow's milk contain all essential amino acids. Peanuts, soy milk, nuts, seeds, green peas, Legumes, the alga spirulina and some grains are some of the richest sources of plant protein. Proteins differ from carbohydrates chiefly in that they contain much nitrogen and a little bit of sulfur, besides carbon, oxygen and hydrogen. Biochemistry A protein molecule is an unbranched biopolymer composed of many amino acids linked together in a chain. The chain folds into a 3-dimensional structure known as the native state, which is determined by its sequence of amino acids. There are four levels of protein structure: Primary structure: the amino acid sequence Secondary structure: structures.
Prime Directive - evidence of advanced technology is left behind and they do not reveal their identity. It appears that the non-interference concept originated with Vulcanss and predated the formation of the United Federation of Planets. Discussion Star Trek stories have used the Prime Directive as a literary contrivance which allows the exploration of interactions with less advanced societies without the heroes having the overwhelming advantage of easy access and use of their technology. Since Star Trek has consistently used alien interactions as an allegory for the real world, the Prime Directive has served as a template to tell stories which resemble those of real human societies and their interactions with less techonologically advanced societies, such as the interaction between advanced cultures and indigenous peoples. In the philosophical view of Star Trek, no matter.
Proteomics - much more complicated than genomics. Most importantly, while the genome is a rather constant entity, the proteome is constantly changing through its biochemical interactions with the genome. One organism will have radically different protein expression in different parts of its body and in different stages of its life cycle. The entirety of proteins in existence in an organism throughout its life cycle, or on a smaller scale the entirety of proteins found in a particular cell type under a particular type of stimulation, are referred to as the Proteome of the organism or cell type respectively. With completion of a rough draft of the human genome, many researchers are now looking at how genes and proteins interact to form other proteins. A surprising finding of the Human Genome Project is that.
Predestination paradox - been given in various works of literature and film for various circumstances that arise. The idea is that when one travels back in time, one may influence events while in the past. These interactions have a direct effect, usually bad for purposes of the plot, on the future and the time traveller. The famous example is of a person going back and killing his own grandfather before his parent is born, forcing himself to not exist (the grandfather paradox). In many cases, the causal loop has been used as a means in and of itself to provide a plot, and sometimes time travel is not even directly involved. Suppose a man travels back in time and impregnates his great-great grandmother. The grandmother would thus give birth to one of the man's.
October 2003 - Irish-based Australian novelist D.B.C. Pierre (real name Peter Finlay) wins the 2003 Booker prize with his first novel, Vernon God Little, a satire on a Texas high-school massacre.

Nudism - be examples of true nudism. Some nudist organizations do not allow people with body piercings on their premises (presumably this rule refers to the foreign objects in the piercings, not to the piercings themselves). Most however accept people of all sizes, shapes and types including those with surgical scars, tattoos or interestingly trimmed (or absence of) hair. Some nudist organizations do not allow unaccompanied men, see e.g. [1]. Nudism is not equivalent to exhibitionism. It is people who enjoy being nude and who are not primarily interested in seeing others naked or being seen naked by others. That being said, all kinds of people are attracted to the movement, for all kinds of reasons. Many naturists are convinced that increased exposure to the natural environment, made easier through nudity, can result.
Molecular biology - The field overlaps with other areas of biology, particularly genetics and biochemistry. Molecular biology chiefly concerns itself with understanding the interactions between the various systems of a cell, including the interrelationship of DNA, RNA and protein synthesis and learning how these interactions are regulated. Writing in Nature, W.T. Astbury described molecular biology as: "... not so much a technique as an approach, an approach from the viewpoint of the so-called basic sciences with the leading idea of searching below the large-scale manifestations of classical biology for the corresponding molecular plan. It is concerned particularly with the forms of biological molecules and ..... is predominantly three-dimensional and structural - which does not mean, however, that it is merely a refinement of morphology - it must at the same time inquire into genesis.
Lamanite - a wealthy Jewish merchant, who traveled from the Middle East in 600 BC to the Americas by boat. Nephites descended from the youngest son, Nephi, while Lamanites descended from the elder brothers, Laman and Lemuel. According to the Book of Mormon there were many interactions between the Lamanites and the Nephites. Activities from war to trade to proselytizing were used by each one on the other to varying degrees and at different stages in their histories. The actual ethnic make up of each group seems to have shifted as the story progresses. The Lamanites initially are given a darker skin color from God due to their rebellion. At one point in the book the Lamanites and Nephites coexist for two centuries in peace (from about 30 AD to 230 AD) Shortly.
International Treaty on Plant Genetic Resources for Food and Agriculture - International Treaty on Plant Genetic Resources for Food and Agriculture The International Treaty on Plant Genetic Resources for Food and Agriculture is a comprehensive international agreement which aims at guaranteeing food security through the conservation, exchange and sustainable use of the world's plant genetic resources, as well as the fair use and equitable benefit sharing, in harmony with Convention on Biological Diversity. It also recognises the Farmers’ Rights to freely access genetic resources, to use and save seeds, under national laws. The Treaty will implement a Multilateral System of access to a list of 64 of the most important food and forage crops essential for food security and interdependence for those countries that ratify the treaty. It includes a funding mechanism that receives shares arising from the commercial utilization.
Inheritance (genetic algorithm) - Inheritance (genetic algorithm) In genetic algorithms, inheritance is the ability of modelled objects to mate, mutate and propagate their problem solving genes to the next generation, in order to produce an evolved solution to a particular problem..
