Bodo Saltans Virus
The Bodo saltans virus is a giant virus of the ''Mimiviridae'' family that infects the protozoa ''Bodo saltans''. It has a genome of 1.39 megabases A base pair (bp) is a fundamental unit of double-stranded nucleic acids consisting of two nucleobases bound to each other by hydrogen bonds. They form the building blocks of the DNA double helix and contribute to the folded structure of both DN ..., one of the largest known viral genomes. References Mimiviridae {{Virus-stub ...

Bodo Saltans
''Bodo saltans'' (alternatively known as ''Pleuromonas jaculans'') is a free-living nonparasitic species of kinetoplastid flagellated phagotrophic protozoa that feed on bacteria. ''Bodo saltans'' cells have been reported in freshwater and marine environments. ''Bodo saltans'' is a single-celled bean-shaped organism 4 to 5 micrometers in length. It has two flagella: a short anterior projecting flagellum and a longer posterior-projecting flagellum without hairs (acronematic) that extends beyond the length of the cell. ''B. saltans'' secures itself to the substrate of its aquatic habitat by the tip of a posterior flagellum. Flexing of the posterior flagellum results in a twitching, jumping movement that is characteristic of this species. This type of movement appears similar to the undulating membrane of the sexually-transmitted pathogen ''Trichomonas vaginalis'' and can result in a false-positive diagnosis in cases where ''B. saltans'' is a contaminant in test samples, especially if ...

Giant Virus
A giant virus, sometimes referred to as a girus, is a very large virus, some of which are larger than typical bacteria. All known giant viruses belong to the phylum ''Nucleocytoviricota''. Description While the exact criteria as defined in the scientific literature vary, giant viruses are generally described as viruses having large, pseudo- icosahedral capsids (200 to 400 nanometers in diameter) that may be surrounded by a thick (approximately 100 nm) layer of filamentous protein fibers. The viruses have large, double-stranded DNA genomes (300 to >1000 kilobasepairs) that encode a large contingent of genes (of the order of 1000 genes). The best characterized giant viruses are the phylogenetically related mimivirus and megavirus, which belong to the family ''Mimiviridae'' (aka ''Megaviridae''), and are distinguished by their large capsid diameters. Giant viruses from the deep ocean, terrestrial sources, and human patients contain genes encoding Cytochrome P450, cytochrome P45 ...

Mimiviridae
''Mimiviridae'' is a family of viruses. Amoeba and other protists serve as natural hosts. The family is divided in up to 4 subfamilies., UCPMS ID: 1889607PDF/ref> Fig. 4 and §Discussion: "Considering that tupanviruses comprise a sister group to amoebal mimiviruses…" Viruses in this family belong to the nucleocytoplasmic large DNA virus clade (NCLDV), also referred to as giant viruses. ''Mimiviridae'' is the sole recognized member of order ''Imitervirales''. ''Phycodnaviridae'' and ''Pandoraviridae'' of ''Algavirales'' are sister groups of ''Mimiviridae'' in many phylogenetic analyses. History The first member of this family, Mimivirus, was discovered in 2003, and the first complete genome sequence was published in 2004. However, the mimivirus Cafeteria roenbergensis virus was isolated and partially characterized in 1995, although the host was misidentified at the time, and the virus was designated BV-PW1. Taxonomy Group: dsDNA Family ''Mimiviridae'' is currently div ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protozoa
Protozoa (singular: protozoan or protozoon; alternative plural: protozoans) are a group of single-celled eukaryotes, either free-living or parasitic, that feed on organic matter such as other microorganisms or organic tissues and debris. Historically, protozoans were regarded as "one-celled animals", because they often possess animal-like behaviours, such as motility and predation, and lack a cell wall, as found in plants and many algae. When first introduced by Georg Goldfuss (originally spelled Goldfuß) in 1818, the taxon Protozoa was erected as a class within the Animalia, with the word 'protozoa' meaning "first animals". In later classification schemes it was elevated to a variety of higher ranks, including phylum, subkingdom and kingdom, and sometimes included within Protoctista or Protista. The approach of classifying Protozoa within the context of Animalia was widespread in the 19th and early 20th century, but not universal. By the 1970s, it became usual to require th ...

Genome
In the fields of molecular biology and genetics, a genome is all the genetic information of an organism. It consists of nucleotide sequences of DNA (or RNA in RNA viruses). The nuclear genome includes protein-coding genes and non-coding genes, other functional regions of the genome such as regulatory sequences (see non-coding DNA), and often a substantial fraction of 'junk' DNA with no evident function. Almost all eukaryotes have mitochondria and a small mitochondrial genome. Algae and plants also contain chloroplasts with a chloroplast genome. The study of the genome is called genomics. The genomes of many organisms have been sequenced and various regions have been annotated. The International Human Genome Project reported the sequence of the genome for ''Homo sapiens'' in 200The Human Genome Project although the initial "finished" sequence was missing 8% of the genome consisting mostly of repetitive sequences. With advancements in technology that could handle sequenci ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Megabases
A base pair (bp) is a fundamental unit of double-stranded nucleic acids consisting of two nucleobases bound to each other by hydrogen bonds. They form the building blocks of the DNA double helix and contribute to the folded structure of both DNA and RNA. Dictated by specific hydrogen bonding patterns, "Watson–Crick" (or "Watson–Crick–Franklin") base pairs (guanine–cytosine and adenine–thymine) allow the DNA helix to maintain a regular helical structure that is subtly dependent on its nucleotide sequence. The complementary nature of this based-paired structure provides a redundant copy of the genetic information encoded within each strand of DNA. The regular structure and data redundancy provided by the DNA double helix make DNA well suited to the storage of genetic information, while base-pairing between DNA and incoming nucleotides provides the mechanism through which DNA polymerase replicates DNA and RNA polymerase transcribes DNA into RNA. Many DNA-binding protei ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lax 33014 Elife-33014-fig2-figsupp1-v1C
Los Angeles International Airport , commonly referred to as LAX (with each letter pronounced individually), is the primary international airport serving Los Angeles, California and its surrounding metropolitan area. LAX is located in the Westchester neighborhood of Los Angeles, southwest of Downtown Los Angeles, with the commercial and residential areas of Westchester to the north, the city of El Segundo to the south and the city of Inglewood to the east. LAX is the closest airport to the Westside and the South Bay. The airport is operated by Los Angeles World Airports (LAWA), a branch of the Los Angeles city government, that also operates Van Nuys Airport for general aviation. The airport covers of land and has four parallel runways. In 2019, LAX handled 88,068,013 passengers, making it the world's third-busiest and the United States' second-busiest airport following Hartsfield–Jackson Atlanta International Airport.
