Reference Genome
A reference genome (also known as a reference assembly) is a digital nucleic acid sequence database, assembled by scientists as a representative example of the set of genes in one idealized individual organism of a species. As they are assembled from the sequencing of DNA from a number of individual donors, reference genomes do not accurately represent the set of genes of any single individual organism. Instead a reference provides a haploid mosaic of different DNA sequences from each donor. For example, the most recent human reference genome (assembly '' GRCh38/hg38'') is derived from >60 genomic clone libraries. There are reference genomes for multiple species of viruses, bacteria, fungus, plants, and animals. Reference genomes are typically used as a guide on which new genomes are built, enabling them to be assembled much more quickly and cheaply than the initial Human Genome Project. Reference genomes can be accessed online at several locations, using dedicated browsers s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Contig
A contig (from ''contiguous'') is a set of overlapping DNA segments that together represent a consensus region of DNA.Gregory, S. ''Contig Assembly''. Encyclopedia of Life Sciences, 2005. In bottom-up sequencing projects, a contig refers to overlapping sequence data ( reads); in top-down sequencing projects, contig refers to the overlapping clones that form a physical map of the genome that is used to guide sequencing and assembly.Dear, P. H. ''Genome Mapping''. Encyclopedia of Life Sciences, 2005. . Contigs can thus refer both to overlapping DNA sequences and to overlapping physical segments (fragments) contained in clones depending on the context. Original definition of contig In 1980, Staden wrote: ''In order to make it easier to talk about our data gained by the shotgun method of sequencing we have invented the word "contig". A contig is a set of gel readings that are related to one another by overlap of their sequences. All gel readings belong to one and only one con ...

Buffalo, New York
Buffalo is the second-largest city in the U.S. state of New York (behind only New York City) and the seat of Erie County. It is at the eastern end of Lake Erie, at the head of the Niagara River, and is across the Canadian border from Southern Ontario. With a population of 278,349 according to the 2020 census, Buffalo is the 78th-largest city in the United States. The city and nearby Niagara Falls together make up the two-county Buffalo–Niagara Falls Metropolitan Statistical Area (MSA), which had an estimated population of 1.1 million in 2020, making it the 49th largest MSA in the United States. Buffalo is in Western New York, which is the largest population and economic center between Boston and Cleveland. Before the 17th century, the region was inhabited by nomadic Paleo-Indians who were succeeded by the Neutral, Erie, and Iroquois nations. In the early 17th century, the French began to explore the region. In the 18th century, Iroquois land surrounding Buffalo Creek ...

McDonnell Genome Institute
McDonnell Genome Institute (The Elizabeth H. and James S. McDonnell III Genome Institute) at Washington University in St. Louis, Missouri, is one of three Nih, NIH funded large-scale sequencing centers in the United States. Affiliated with Washington University School of Medicine and the Alvin J. Siteman Cancer Center, the McDonnell Genome Institute is creating, testing and implementing new approaches to the study of genomics with the goal of understanding human health and disease, as well as evolution and the biology of other organisms.

Sanger Institute
The Wellcome Sanger Institute, previously known as The Sanger Centre and Wellcome Trust Sanger Institute, is a non-profit organisation, non-profit British genomics and genetics research institute, primarily funded by the Wellcome Trust. It is located on the Wellcome Genome Campus by the village of Hinxton, outside Cambridge. It shares this location with the European Bioinformatics Institute. It was established in 1992 and named after double Nobel Laureate Frederick Sanger. It was conceived as a large scale DNA sequencing centre to participate in the Human Genome Project, and went on to make the largest single contribution to the gold standard sequence of the human genome. From its inception the institute established and has maintained a policy of data sharing, and does much of its research in collaboration. Since 2000, the institute expanded its mission to understand "the role of genetics in health and disease". The institute now employs around 900 people and engages in five mai ...

Genome Reference Consortium
The Genome Reference Consortium (GRC) is an international collective of academic and research institutes with expertise in genome mapping, sequencing, and informatics, formed to improve the representation of reference genomes. At the time the Human Genome Project, human reference was initially described, it was clear that some regions were recalcitrant to analysis with existing technology, leaving gaps in the known sequence. The main reason for improving the reference assembly, reference assemblies are that they are the cornerstones upon which all whole genome studies are based (e.g. the 1000 Genomes Project). The GRC is a collaborative effort which interacts with various groups in the scientific community. The primary member institutes are: * The Wellcome Sanger Institute * The McDonnell Genome Institute at Washington University * The European Bioinformatics Institute * The National Center for Biotechnology Information * Zebrafish Model Organism Database * Rat Genome Database Th ...

N50, L50, And Related Statistics
In computational biology, N50 and L50 are statistics of a set of contig or scaffold lengths. The ''N50'' is similar to a mean or median of lengths, but has greater weight given to the longer contigs. It is used widely in genome assembly, especially in reference to contig lengths within a draft assembly. There are also the related U50, UL50, UG50, UG50%, N90, NG50, and D50 statistics. To provide a better assessment of assembly output for viral and microbial datasets, a new metric called U50 should be used. The ''U50'' identifies unique, target-specific contigs by using a reference genome as baseline, aiming at circumventing some limitations that are inherent to the ''N50'' metric. The use of the ''U50'' metric allows for a more accurate measure of assembly performance by analyzing only the unique, non-overlapping contigs. Most viral and microbial sequencing have high background noise (i.e., host and other non-targets), which contributes to having a skewed, misrepresented ''N50'' v ...

Scaffolding
Scaffolding, also called scaffold or staging, is a temporary structure used to support a work crew and materials to aid in the construction, maintenance and repair of buildings, bridges and all other man-made structures. Scaffolds are widely used on site to get access to heights and areas that would be otherwise hard to get to. Unsafe scaffolding has the potential to result in death or serious injury. Scaffolding is also used in adapted forms for formwork and shoring, grandstand seating, concert stages, access/viewing towers, exhibition stands, ski ramps, half pipes and art projects. There are five main types of scaffolding used worldwide today. These are tube and coupler (fitting) components, prefabricated modular system scaffold components, H-frame / façade modular system scaffolds, timber scaffolds and bamboo scaffolds (particularly in China and India). Each type is made from several components which often include: * A base jack or plate which is a load-bearing base for the ...
