An oligonucleotide from Greek Language Greek prefix oligo , having few, having little is a short nucleic acid polymer , typically with fifty or fewer nucleotide bases . Although they can be formed by bond cleavage of longer segments, they are now more commonly oligonucleotidesynthesis synthesized , in a sequence specific manner, from individual Nucleoside phosphoramidite nucleoside phosphoramidites . Automated synthesizers allow the synthesis of oligonucleotides up to about 200 bases. Oligonucleotides are characterized by the Nucleic acid sequence sequence of nucleotide residues that comprise the entire molecule. The length of the oligonucleotide is usually denoted by Monomer mer from Greek Language Greek meros , part . For example, a fragment of 25 bases would be called a 25 mer. Oligonucleotides readily bind, in a sequence specific manner, to their respective Complementarity molecular biology complementary oligonucleotides, DNA, or RNA to form Nucleic acid thermodynamics Concepts duplexes or, less often, hybrids of a higher order.

An allele specific oligonucleotide ASO is a short piece of synthetic DNA complementary to the sequence of a variable target DNA. It acts as a Hybridization probe probe for the presence of the target in a Southern blot assay or, more commonly, in the simpler Dot blot assay. It is a common tool used in genetic testing , forensics , and Molecular Biology research. An ASO is typically an oligonucleotide of 15 21 nucleotide nucleotide bases in length. It is designed and used in a way that makes it specific for only one version, or allele , of the DNA being tested. The length of the ASO, which strand it is chosen from, and the conditions by which it is Nucleic acid hybridization bound to and washed from the target DNA all play a role in its specificity. These probes can usually be designed to detect a difference of as little as 1 base in the target s genetic sequence, a basic ability in the assay of single nucleotide polymorphism s SNPs , important in genotype genotype analysis and the Human Genome Project . To be detected after it has bound to its target, the ASO must be labeled with a radioactive, enzymatic, or fluorescent tag. The Illumina Methylation Assay technology takes advantage of ASO to detect one base pair difference cytosine versus thymine to measure methylation at a specific CpG site.

Expert subject Genetics date February 2009 Image ROMA.jpg right 270px thumb ROMA. Representational oligonucleotide microarray analysis ROMA is a technique that was developed by Michael Wigler and Rob Lucito at the Cold Spring Harbor Laboratory CSHL in 2003. Fact date July 2008 Wigler and Lucito currently run laboratories at CSHL using ROMA to explore genomic copy number variation in cancer and other genetic diseases. In this technique, two genome s are compared for their differences in copy number on a microarray. The ROMA technology emerged from a previous method called Representational Difference Analysis RDA . ROMA, in comparison to other comparative genomic hybridization CGH techniques, has the advantage of reducing the complexity of a genome with a restriction enzyme which highly increases the efficiency of genomic fragment hybridization to a microarray. In ROMA, a genome is digested with a restriction enzyme, ligated with adapters specific to the restriction fragment sticky ends and amplified by PCR. After the PCR step, representations of the entire genome restriction fragments are amplified to pronounce relative increases, decreases or preserve equal copy number in the two genomes. The representations of the two different genomes are labeled with different fluorophores and co hybridized to a microarray with probes specific to locations across the entire human genome. After analysis of the ROMA microarray image is completed, a copy number profile of the entire human genome is generated. This allows researchers to detect with high accuracy amplifications amplicons and deletions that occur across the entire genome. In cancer, the genome becomes very unstable, resulting in specific regions that may be deleted if they contain a tumor suppressor or amplified if they contain an oncogene . Amplifications and deletions have also been observed in the normal human population ..., R. et al. 2003 Representational oligonucleotide microarray analysis a high resolution method to detect ... more details

In chemistry a convergent synthesis is a strategy that aims to improve the efficiency of multi step chemical synthesis , most often in organic synthesis . In linear synthesis the overall chemical yield yield quickly drops with each reaction step A B C D Suppose the yield is 50 for each reaction, the overall yield of D is only 12.5 from A. In a convergent synthesis A B 50 C D 50 B D E 25 the overall yield of E 25 looks much better.

In chemistry a divergent synthesis is a strategy with the aim to improve the efficiency of chemical synthesis . It is often an alternative to convergent synthesis or linear synthesis. In one strategy divergent synthesis aims to generate a library biology library of chemical compound s by first reacting a molecule with a set of reactants. The next generation of compounds is generated by further reactions with each compound in generation 1. This methodology quickly diverges to large numbers of new compounds A generates A1, A2, A3, A4, A5 in generation 1 A1 generates A11, A12, A13 in generation 2 and so on. An entire library of new chemical compounds for instance carbohydrate sugar s can be screened for desirable properties. In another strategy divergent synthesis starts from a molecule as a central core from which successive generations of building blocks are added. A good example is the divergent synthesis of dendrimer s for example where in each generation new monomer reacts to the growing surface of the sphere. Diversity Oriented Synthesis Diversity oriented synthesis or DOS is a strategy for quick access to molecule libraries with an emphasis on skeletal diversity. ref cite journal title A Planning Strategy for Diversity Oriented Synthesis last1 Burke first1 Martin last2 Schreiber first2 Stuart journal Angewandte Chemie International Edition year 2004 volume 43 issue 1 pages 46 doi 10.1002 anie.200300626 pmid 14694470 ref In one such application a Petasis reaction product 1 .... ref Short Synthesis of Skeletally and Stereochemically Diverse Small Molecules by Coupling Petasis ... ref Image DivergentPetasis.png 500px center Short Synthesis of Skeletally and Stereochemically ... links Diversity Oriented Synthesis Journal http versita.com dos Link Divergent synthesis in sugars ... synthesis http www2.chemie.uni erlangen.de services dissonline data dissertation Francesc Camprubi html chapter3 3.html Link References Reflist DEFAULTSORT Divergent Synthesis Category Chemical synthesis ... more details

The goal of intellectual synthesis is to bring together all of the related transdisciplinary knowledge into a single, cohesive whole to provide for a more complete and comprehensive understanding and potentially lead to new theories, perspectives, and interpretations. Many new and emerging fields involve intellectual synthesis Big history World History Sociobiology Geographical determinism Environmental Determinism Technological Determinism Related Books The topic of intellectual synthesis is the subject of many books, as often proponents of the need for such a scholarly endeavor will use a written work to voice their call ... more details
