D. Radiodurans
''Deinococcus radiodurans'' is a bacterium, an extremophile and one of the most radiation-resistant organisms known. It can survive cold, dehydration, vacuum, and acid, and therefore is known as a polyextremophile. ''The Guinness Book Of World Records'' listed it in January 1998 as the world's most radiation-resistant bacterium or lifeform. Several bacteria of comparable radioresistance are known, including some species of the genus '' Chroococcidiopsis'' (phylum cyanobacteria) and some species of ''Rubrobacter'' (phylum Actinomycetota); among the archaea, the species ''Thermococcus gammatolerans'' shows comparable radioresistance. Name and classification The name ''Deinococcus radiodurans'' derives from the Ancient Greek δεινός () and κόκκος () meaning "terrible grain/berry" and the Latin and , meaning "radiation-surviving". The species was formerly called ''Micrococcus radiodurans''. As a consequence of its hardiness, it has been nicknamed “Conan the Bacterium†...

Bacterium
Bacteria (; : 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 the air, soil, water, acidic hot springs, radioactive waste, and the deep biosphere of Earth's crust. Bacteria play a vital role in many stages of the nutrient cycle by recycling nutrients and 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 mutualistic, commensal and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Conan The Barbarian
Conan the Barbarian (also known as Conan the Cimmerian) is a fictional sword and sorcery hero created by American author Robert E. Howard (1906–1936) and who debuted in 1932 and went on to appear in a series of fantasy stories published in ''Weird Tales'' magazine. After first appearing in pulp magazines, the character has since been adapted to Conan (books), books, Conan (comics), comics, films (including ''Conan the Barbarian (1982 film), Conan the Barbarian'' and ''Conan the Destroyer''), television programs (Conan the Adventurer (1992 TV series), animated and Conan the Adventurer (1997 TV series), live action), Conan (game)#Video games, video games, and role-playing games. The earliest appearance of a Robert E. Howard character named Conan was that of a black-haired barbarian with heroic attributes in the 1931 short story "People of the Dark". Before Howard's death he wrote 21 stories starring the barbarian. Over the years, many other writers have written works featuring Co ...

DNA Sequence
A nucleic acid sequence is a succession of bases within the nucleotides forming alleles within a DNA (using GACT) or RNA (GACU) molecule. This succession is denoted by a series of a set of five different letters that indicate the order of the nucleotides. By convention, sequences are usually presented from the 5' end to the 3' end. For DNA, with its double helix, there are two possible directions for the notated sequence; of these two, the sense strand is used. Because nucleic acids are normally linear (unbranched) polymers, specifying the sequence is equivalent to defining the covalent structure of the entire molecule. For this reason, the nucleic acid sequence is also termed the primary structure. The sequence represents genetic information. Biological deoxyribonucleic acid represents the information which directs the functions of an organism. Nucleic acids also have a secondary structure and tertiary structure. Primary structure is sometimes mistakenly referred to as "prim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gamma Radiation
A gamma ray, also known as gamma radiation (symbol ), is a penetrating form of electromagnetic radiation arising from high energy interactions like the radioactive decay of atomic nuclei or astronomical events like solar flares. It consists of the shortest wavelength electromagnetic waves, typically shorter than those of X-rays. With frequencies above 30 exahertz () and wavelengths less than 10 picometers (), gamma ray photons have the highest photon energy of any form of electromagnetic radiation. Paul Villard, a French chemist and physicist, discovered gamma radiation in 1900 while studying radiation emitted by radium. In 1903, Ernest Rutherford named this radiation ''gamma rays'' based on their relatively strong penetration of matter; in 1900, he had already named two less penetrating types of decay radiation (discovered by Henri Becquerel) alpha rays and beta rays in ascending order of penetrating power. Gamma rays from radioactive decay are in the energy range ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Thermophile
A thermophile is a type of extremophile that thrives at relatively high temperatures, between . Many thermophiles are archaea, though some of them are bacteria and fungi. Thermophilic eubacteria are suggested to have been among the earliest bacteria. Thermophiles are found in geothermally heated regions of the Earth, such as hot springs like those in Yellowstone National Park and deep sea hydrothermal vents, as well as decaying plant matter, such as peat bogs and compost. They can survive at high temperatures, whereas other bacteria or archaea would be damaged and sometimes killed if exposed to the same temperatures. The enzymes in thermophiles function at high temperatures. Some of these enzymes are used in molecular biology, for example the ''Taq'' polymerase used in PCR. "Thermophile" is derived from the (''thermotita''), meaning heat, and (''philia''), love. Comparative surveys suggest that thermophile diversity is principally driven by pH, not temperature.

Type Species
In International_Code_of_Zoological_Nomenclature, zoological nomenclature, a type species (''species typica'') is the species name with which the name of a genus or subgenus is considered to be permanently taxonomically associated, i.e., the species that contains the biological Type (biology), type wiktionary:en:specimen, specimen (or specimens). Article 67.1 A similar concept is used for suprageneric groups and called a type genus. In botanical nomenclature, these terms have no formal standing under the International Code of Nomenclature for algae, fungi, and plants, code of nomenclature, but are sometimes borrowed from zoological nomenclature. In botany, the type of a genus name is a specimen (or, rarely, an illustration) which is also the type of a species name. The species name with that type can also be referred to as the type of the genus name. Names of genus and family ranks, the various subdivisions of those ranks, and some higher-rank names based on genus names, have suc ...

Thermus
''Thermus'' is a genus of thermophilic bacteria. It is one of several bacteria belonging to the ''Deinococcota'' phylum. According to comparative analysis of 16S rRNA, this is one of the most ancient group of bacteria. ''Thermus'' species can be distinguished from other genera in the family ''Thermaceae'' as well as all other bacteria by the presence of eight conserved signature indels found in proteins such as adenylate kinase and replicative DNA helicase as well as 14 conserved signature proteins that are exclusively shared by members of this genus. Phylogeny The currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) and the National Center for Biotechnology Information (NCBI). Between all its species, '' T. thermophilus'' has a special importance as a model organism for basic and applied research.
