Paris
Paris () is the capital and most populous city of France, with an estimated population of 2,165,423 residents in 2019 in an area of more than 105 km² (41 sq mi), making it the 30th most densely populated city in the world in 2020. Since the 17th century, Paris has been one of the world's major centres of finance, diplomacy, commerce, fashion, gastronomy, and science. For its leading role in the arts and sciences, as well as its very early system of street lighting, in the 19th century it became known as "the City of Light". Like London, prior to the Second World War, it was also sometimes called the capital of the world. The City of Paris is the centre of the Île-de-France region, or Paris Region, with an estimated population of 12,262,544 in 2019, or about 19% of the population of France, making the region France's primate city. The Paris Region had a GDP of €739 billion ($743 billion) in 2019, which is the highest in Europe. According to the Economist Intelli ...

Journal Of Cell Biology
The ''Journal of Cell Biology'' is a peer-reviewed scientific journal published by Rockefeller University Press. History In the early 1950s, a small group of biologists began to explore intracellular anatomy using the emerging technology of electron microscopy. Many of these researchers were at The Rockefeller Institute of Medicine, the predecessor of The Rockefeller University. As their work progressed to publication, they were disappointed with the limited quality of halftone image reproduction in the printed journals of the time, and frustrated by the narrow editorial policies of existing journals regarding their image-based results. In 1954, the Director of the Rockefeller Institute, Detlev Bronk, convened a luncheon to discuss the creation of a new journal as a venue for publication of this type of work. The first issue of ''The Journal of Biophysical and Biochemical Cytology'' was published less than a year later on January 25, 1955. A subscription cost $15 per year. The l ...

NDUFS1
NADH-ubiquinone oxidoreductase 75 kDa subunit, mitochondrial (NDUFS1) is an enzyme that in humans is encoded by the ''NDUFS1'' gene. The encoded protein, NDUFS1, is the largest subunit of complex I, located on the inner mitochondrial membrane, and is important for mitochondrial oxidative phosphorylation. Mutations in this gene are associated with complex I deficiency. Structure ''NDUFS1'' is located on the q arm of chromosome 2 in position 33.3 and has 20 exons. The ''NDUFS1'' gene produces a 79.5 kDa protein composed of 727 amino acids. NDUFS1, the protein encoded by this gene, is a member of the complex I 75 kDa subunit family. It contains a transit peptide, 10 turns, 19 beta strands, 27 alpha helixes, and cofactor binding sites for 2Fe-2S_cluster">2Fe-2S.html" ;"title="2Fe-2S_cluster.html" ;"title="nowiki/>2Fe-2S cluster">2Fe-2S">2Fe-2S_cluster.html" ;"title="nowiki/>2Fe-2S cluster">2Fe-2Sand [4Fe-4S] clusters.

COS Cells
COS are fibroblast-like cell lines derived from monkey kidney tissue. COS cells are obtained by immortalizing CV-1 cells with a version of the SV40 virus that can produce large T antigen but has a defect in genomic replication. The CV-1 cell line in turn was derived from the kidney of the African green monkey. The acronym "COS" is derived from the cells being CV-1 (simian) in Origin, and carrying the SV40 genetic material. Three COS lines were created (COS-1, COS-3 and COS-7), of which two are commonly used (COS-1 and COS-7). Applications The COS cell lines are often used by biologists when studying the monkey virus SV40. Cells from these lines are also often transfected to produce recombinant proteins for molecular biology, biochemistry, and cell biology experiments. When an expression construct with an SV40 origin of replication is introduced into COS cells, the vector can be replicated substantially by the large T antigen The large tumor antigen (also called the large T-an ...

Transcription Factor
In molecular biology, a transcription factor (TF) (or sequence-specific DNA-binding factor) is a protein that controls the rate of transcription of genetic information from DNA to messenger RNA, by binding to a specific DNA sequence. The function of TFs is to regulate—turn on and off—genes in order to make sure that they are expressed in the desired cells at the right time and in the right amount throughout the life of the cell and the organism. Groups of TFs function in a coordinated fashion to direct cell division, cell growth, and cell death throughout life; cell migration and organization (body plan) during embryonic development; and intermittently in response to signals from outside the cell, such as a hormone. There are up to 1600 TFs in the human genome. Transcription factors are members of the proteome as well as regulome. TFs work alone or with other proteins in a complex, by promoting (as an activator), or blocking (as a repressor) the recruitment of RNA ...

Molecular Biology
Molecular biology is the branch of biology that seeks to understand the molecular basis of biological activity in and between cells, including biomolecular synthesis, modification, mechanisms, and interactions. The study of chemical and physical structure of biological macromolecules is known as molecular biology. Molecular biology was first described as an approach focused on the underpinnings of biological phenomena - uncovering the structures of biological molecules as well as their interactions, and how these interactions explain observations of classical biology. In 1945 the term molecular biology was used by physicist William Astbury. In 1953 Francis Crick, James Watson, Rosalind Franklin, and colleagues, working at Medical Research Council unit, Cavendish laboratory, Cambridge (now the MRC Laboratory of Molecular Biology), made a double helix model of DNA which changed the entire research scenario. They proposed the DNA structure based on previous research done by Ro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Homeotic Gene
In evolutionary developmental biology, homeotic genes are genes which regulate the development of anatomical structures in various organisms such as echinoderms, insects, mammals, and plants. Homeotic genes often encode transcription factor proteins, and these proteins affect development by regulating downstream gene networks involved in body patterning. Mutations in homeotic genes cause displaced body parts (homeosis), such as antennae growing at the posterior of the fly instead of at the head. Mutations that lead to development of ectopic structures are usually lethal. Types There are several subsets of homeotic genes. They include many of the Hox and ParaHox genes that are important for segmentation. Hox genes are found in bilateral animals, including ''Drosophila'' (in which they were first discovered) and humans. Hox genes are a subset of the homeobox genes. The Hox genes are often conserved across species, so some of the Hox genes of ''Drosophila'' are homologous to thos ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
