Plasmid
A plasmid is a small, extrachromosomal DNA molecule within a cell that is physically separated from chromosomal DNA and can replicate independently. They are most commonly found as small circular, double-stranded DNA molecules in bacteria; however, plasmids are sometimes present in archaea and eukaryotic organisms. In nature, plasmids often carry genes that benefit the survival of the organism and confer selective advantage such as antibiotic resistance. While chromosomes are large and contain all the essential genetic information for living under normal conditions, plasmids are usually very small and contain only additional genes that may be useful in certain situations or conditions. Artificial plasmids are widely used as vectors in molecular cloning, serving to drive the replication of recombinant DNA sequences within host organisms. In the laboratory, plasmids may be introduced into a cell via transformation. Synthetic plasmids are available for procurement over the inter ...

Motor Neuron Disease
Amyotrophic lateral sclerosis (ALS), also known as motor neuron disease (MND) or Lou Gehrig's disease, is a neurodegenerative disease that results in the progressive loss of motor neurons that control voluntary muscles. ALS is the most common type of motor neuron diseases. Early symptoms of ALS include stiff muscles, muscle twitches, and gradual increasing weakness and muscle wasting. ''Limb-onset ALS'' begins with weakness in the arms or legs, while ''bulbar-onset ALS'' begins with difficulty speaking or swallowing. Half of the people with ALS develop at least mild difficulties with thinking and behavior, and about 15% develop frontotemporal dementia. Most people experience pain. The affected muscles are responsible for chewing food, speaking, and walking. Motor neuron loss continues until the ability to eat, speak, move, and finally the ability to breathe is lost. ALS eventually causes paralysis and early death, usually from respiratory failure. Most cases of ALS (abou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FUS (gene)
RNA-binding protein FUS/TLS (FUused in Sarcoma/Translocated in LipoSarcoma), also known as heterogeneous nuclear ribonucleoprotein P2 is a protein that in humans is encoded by the ''FUS'' gene. Discovery FUS/TLS was initially identified as a fusion protein (FUS-CHOP) produced as a result of chromosomal translocations in human cancers, especially liposarcomas. In these instances, the promoter and N-terminal part of FUS/TLS is translocated to the C-terminal domain of various DNA-binding transcription factors (e.g. CHOP) conferring a strong transcriptional activation domain onto the fusion proteins. FUS/TLS was independently identified as the hnRNP P2 protein, a subunit of a complex involved in the maturation of pre-mRNA. Structure FUS/TLS is a member of the FET protein family that also includes the EWS protein, the TATA-binding protein TBP-associated factor TAFII68/TAF15, and the Drosophila cabeza/SARF protein. FUS/TLS, EWS and TAF15 have a similar structure, characteris ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chromosome 21
Chromosome 21 is one of the 23 pairs of chromosomes in humans. Chromosome 21 is both the smallest human autosome and chromosome, with 48 million base pairs (the building material of DNA) representing about 1.5 percent of the total DNA in cells. Most people have two copies of chromosome 21, while those with three copies of chromosome 21 have Down syndrome, also called "trisomy 21". Researchers working on the Human Genome Project announced in May 2000 that they had determined the sequence of base pairs that make up this chromosome. Chromosome 21 was the second human chromosome to be fully sequenced, after chromosome 22. Genes Number of genes The following are some of the gene count estimates of human chromosome 21. Because researchers use different approaches to genome annotation their predictions of the number of genes on each chromosome varies (for technical details, see gene prediction). Among various projects, the collaborative consensus coding sequence project ( CCDS) take ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Trisomy
A trisomy is a type of polysomy in which there are three instances of a particular chromosome, instead of the normal two. A trisomy is a type of aneuploidy (an abnormal number of chromosomes). Description and causes Most organisms that reproduce sexually have pairs of chromosomes in each cell, with one chromosome inherited from each parent. In such organisms, a process called meiosis creates cells called gametes (eggs or sperm) that have only one set of chromosomes. The number of chromosomes is different for different species. Humans have 46 chromosomes (i.e. 23 pairs of chromosomes). Human gametes have only 23 chromosomes. If the chromosome pairs fail to separate properly during cell division, the egg or sperm may end up with a second copy of one of the chromosomes. (''See'' non-disjunction.) If such a gamete results in fertilization and an embryo, the resulting embryo may also have an entire copy of the extra chromosome. Terminology The number of chromosomes in the cell ...

Dynein
Dyneins are a family of cytoskeletal motor proteins that move along microtubules in cells. They convert the chemical energy stored in ATP to mechanical work. Dynein transports various cellular cargos, provides forces and displacements important in mitosis, and drives the beat of eukaryotic cilia and flagella. All of these functions rely on dynein's ability to move towards the minus-end of the microtubules, known as retrograde transport; thus, they are called "minus-end directed motors". In contrast, most kinesin motor proteins move toward the microtubules' plus-end, in what is called anterograde transport. Classification Dyneins can be divided into two groups: cytoplasmic dyneins and axonemal dyneins, which are also called ciliary or flagellar dyneins. * cytoplasmic ** heavy chain: DYNC1H1, DYNC2H1 ** intermediate chain: DYNC1I1, DYNC1I2 ** light intermediate chain: DYNC1LI1, DYNC1LI2, DYNC2LI1 ** light chain: DYNLL1, DYNLL2, DYNLRB1, DYNLRB2, DYNLT1, DYNLT3 * axo ...

Faculty Of 1000
F1000 (formerly "Faculty of 1000") is an open research publisher for scientists, scholars, and clinical researchers. F1000 offers a different research evaluation service from standard academic journals by offering peer-review after, rather than before, publishing a research article. Initially, F1000 was named after the 1,000 faculty members that performed peer-reviews, but over time F1000 expanded to more than 8,000 members. When F1000 was acquired by Taylor & Francis Group in January 2020, it kept the publishing services. F1000Prime (AKA Faculty Opinions) and F1000 Workspace (AKA Sciwheel) were acquired by different brands. History ''Faculty of 1000'' was founded in 2000 by publishing entrepreneur Vitek Tracz in London. Initially, it was named after the 1,000 experts it had reviewing academic works, but over time F1000 expanded to more than 8,000 members. In 2002, it introduced F1000Prime (later known as Faculty Opinions), which recommended scientific articles selected by its ...
