- Amplicon
Unreferenced stub auto yes date December 2009 image Pcr machine.jpg thumb 75px PCR Thermocycler An amplicon is a piece of DNA formed as the product of natural or artificial amplification events. For example, it can be formed via polymerase chain reaction s PCR or ligase chain reaction s LCR , as well as by natural gene duplication . Artificial amplification can be used to determine sex from a human DNA sample. The locus genetics loci of Alu element insertion is selected, amplified and evaluated in terms of size of the fragment. The sex assay utilizes AluSTXa for the X chromosome, AluSTYa for the Y chromosome, or both AluSTXa and AluSTYa, to reduce the possibility of error to a negligible quantity. The inserted chromosome yields a large fragment when the homologous region is amplified. The males are distinguished as having two DNA amplicons present, while females have only a single amplicon. The kit adapted for carrying out the method includes a pair of primers to amplify the locus and optionally polymerase chain reaction reagents.

- Representation oligonucleotide microarray analysis
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 and are referred to as Copy Number Polymorphisms CNPs . Jonathan Sebat was one of the first rese ... more details

pp move indef small yes Genetics2 DNA sequencing includes several methods and technologies that are used for determining the order of the nucleotide bases adenine , guanine , cytosine , and thymine in a molecule of DNA . Knowledge of DNA sequences has become indispensable for basic biological research, other research branches utilizing DNA sequencing, and in numerous applied fields such as diagnostic, biotechnology , forensic biology and biological systematics . The advent of DNA sequencing has significantly accelerated biological research and discovery. The rapid speed of sequencing attained with modern DNA sequencing technology has been instrumental in the sequencing of the human genome , in the Human Genome Project . Related projects, often by scientific collaboration across continents, have generated the complete DNA sequences of many animal, plant, and microbial genomes.
