Finnlakevirus
''Finnlakeviridae'' is a family of bacterial viruses that is not assigned to any higher taxonomic ranks In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family, order, class, phylum, kingdom, domain. While o .... The family contains a single genus, ''Finnlakevirus'', which contains a single species, ''Flavobacterium virus FLiP''. This virus was isolated in 2010, with its gram-negative host bacterium, from Lake Jyväsjärvi, a boreal freshwater habitat in Central Finland, and is the first described single-stranded DNA virus with an internal membrane. The genome is circular single-stranded DNA of about 9200 nucleotides in length.

Bacteriophage
A bacteriophage (), also known informally as a ''phage'' (), is a duplodnaviria virus that infects and replicates within bacteria and archaea. The term was derived from "bacteria" and the Greek φαγεῖν ('), meaning "to devour". Bacteriophages are composed of proteins that encapsulate a DNA or RNA genome, and may have structures that are either simple or elaborate. Their genomes may encode as few as four genes (e.g. MS2) and as many as hundreds of genes. Phages replicate within the bacterium following the injection of their genome into its cytoplasm. Bacteriophages are among the most common and diverse entities in the biosphere. Bacteriophages are ubiquitous viruses, found wherever bacteria exist. It is estimated there are more than 1031 bacteriophages on the planet, more than every other organism on Earth, including bacteria, combined. Viruses are the most abundant biological entity in the water column of the world's oceans, and the second largest component of biom ...

Taxonomic Rank
In biological classification, taxonomic rank is the relative level of a group of organisms (a taxon) in an ancestral or hereditary hierarchy. A common system consists of species, genus, family (biology), family, order (biology), order, class (biology), class, phylum (biology), phylum, kingdom (biology), kingdom, domain (biology), domain. While older approaches to taxonomic classification were phenomenological, forming groups on the basis of similarities in appearance, organic structure and behaviour, methods based on genetic analysis have opened the road to cladistics. A given rank subsumes under it less general categories, that is, more specific descriptions of life forms. Above it, each rank is classified within more general categories of organisms and groups of organisms related to each other through inheritance of phenotypic trait, traits or features from common ancestors. The rank of any ''species'' and the description of its ''genus'' is ''basic''; which means that to iden ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jyväsjärvi
Lake Jyväsjärvi () is a lake situated in the centre of Jyväskylä in Finland. The lake can be also considered as the Northern end of Lake Päijänne. Parts of Jyväsjärvi have been filled many times to gain more land for the enlarging city of Jyväskylä. Mattilanniemi and Ylistö, two campuses of the University of Jyväskylä are situated on the Southern shores of the lake. Two bridges are crossing the lake connecting Ylistönrinne and Kuokkala neighbourhoods to the city centre. The harbour of Jyväskylä is situated next to the Kuokkala bridge. During winter seasons a three kilometres long ice skating track is created on the surface of the lake. There is also a path, popular among pedestrians, cyclists, joggers and rollerbladers, going around the lake. See also * Päijänne * Jyväskylä Jyväskylä () is a city and municipality in Finland in the western part of the Finnish Lakeland. It is located about 150 km north-east from Tampere, the third largest city in Finl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nucleotide
Nucleotides are organic molecules consisting of a nucleoside and a phosphate. They serve as monomeric units of the nucleic acid polymers – deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are essential biomolecules within all life-forms on Earth. Nucleotides are obtained in the diet and are also synthesized from common nutrients by the liver. Nucleotides are composed of three subunit molecules: a nucleobase, a five-carbon sugar (ribose or deoxyribose), and a phosphate group consisting of one to three phosphates. The four nucleobases in DNA are guanine, adenine, cytosine and thymine; in RNA, uracil is used in place of thymine. Nucleotides also play a central role in metabolism at a fundamental, cellular level. They provide chemical energy—in the form of the nucleoside triphosphates, adenosine triphosphate (ATP), guanosine triphosphate (GTP), cytidine triphosphate (CTP) and uridine triphosphate (UTP)—throughout the cell for the many cellular func ...
