Microsatellite: A microsatellite is a tract of repetitive DNA in which certain DNA motifs (ranging in length from 2–5 base pairs) are repeated, typically 5-50 times. Microsatellites occur at thousands of locations in the human genome and they are notable for their high mutation rate and high diversity in the population.Satellite DNA: Satellite DNA consists of very large arrays of tandemly repeating, non-coding DNA. Satellite DNA is the main component of functional centromeres, and form the main structural constituent of heterochromatin.Trinucleotide repeat disorder: Trinucleotide repeat disorders (also known as trinucleotide repeat expansion disorders, triplet repeat expansion disorders or codon reiteration disorders) are a set of genetic disorders caused by trinucleotide repeat expansion, a kind of mutation where [repeats in certain gene]s exceed the normal, stable threshold, which differs per gene. The mutation is a subset of unstable [[Microsatellite (genetics)|microsatellite repeats that occur throughout all genomic sequences.Infinite alleles model: The infinite alleles model is a mathematical model for calculating genetic mutations. The Japanese geneticist Motoo Kimura and American geneticist James F.Direct repeat: Direct repeats are a type of genetic sequence that consists of two or more repeats of a specific sequence.Thermal cyclerGene polymorphismSymmetry element: A symmetry element is a point of reference about which symmetry operations can take place. In particular, symmetry elements can be centers of inversion, axes of rotation and mirror planes.Chromosome regionsColes PhillipsDNA sequencer: A DNA sequencer is a scientific instrument used to automate the DNA sequencing process. Given a sample of DNA, a DNA sequencer is used to determine the order of the four bases: G (guanine), C (cytosine), A (adenine) and T (thymine).List of sequenced eukaryotic genomesPedigree chart: A pedigree chart is a diagram that shows the occurrence and appearance or phenotypes of a particular gene or organism and its ancestors from one generation to the next,pedigree chart Genealogy Glossary - About.com, a part of The New York Times Company.DNA condensation: DNA condensation refers to the process of compacting DNA molecules in vitro or in vivo. Mechanistic details of DNA packing are essential for its functioning in the process of gene regulation in living systems.Genetic variation: right|thumbTandem repeat: Tandem repeats occur in DNA when a pattern of one or more nucleotides is repeated and the repetitions are directly adjacent to each other. Several protein domains also form tandem repeats within their amino acid primary structure, such as Armadillo repeats.Loss of heterozygosity: Loss of heterozygosity (LOH) is a gross chromosomal event that results in loss of the entire gene and the surrounding chromosomal region.[Association of the autoimmune diseases scleroderma with an immunologic response to cancer,] Christine G.Panmixia: Panmixia (or panmixis) means random mating.King C and Stanfield W.Multiple Loci VNTR Analysis: Multiple Loci VNTR Analysis (MLVA ) is a method employed for the genetic analysis of particular microorganisms, such as pathogenic bacteria, that takes advantage of the polymorphism of tandemly repeated DNA sequences. A "VNTR" is a "variable-number tandem repeat".Replication slippage: Replication slippage, otherwise known as slipped-strand mispairing, is a form of mutation that leads to either a trinucleotide or dinucleotide expansion or contraction during DNA replication.Hartl L.Genetic linkage: Genetic linkage is the tendency of alleles that are located close together on a chromosome to be inherited together during the meiosis phase of sexual reproduction. Genes whose loci are nearer to each other are less likely to be separated onto different chromatids during chromosomal crossover, and are therefore said to be genetically linked.Silent mutation: Silent mutations are mutations in DNA that do not significantly alter the phenotype of the organism in which they occur. Silent mutations can occur in non-coding regions (outside of genes or within introns), or they may occur within exons.GankyrinPanitumumabDNA mismatch repair: DNA mismatch repair is a system for recognizing and repairing erroneous insertion, deletion, and mis-incorporation of bases that can arise during DNA replication and recombination, as well as repairing some forms of DNA damage.BRCT domainHereditary nonpolyposis colorectal cancerBranching order of bacterial phyla (Gupta, 2001): There are several models of the Branching order of bacterial phyla, one of these was proposed in 2001 by Gupta based on conserved indels or protein, termed "protein signatures", an alternative approach to molecular phylogeny. Some problematic exceptions and conflicts are present to these conserved indels, however, they are in agreement with several groupings of classes and phyla.Frameshift mutation: A frameshift mutation (also called a framing error or a reading frame shift) is a genetic mutation caused by indels (insertions or deletions) of a number of nucleotides in a DNA sequence that is not divisible by three. Due to the triplet nature of gene expression by codons, the insertion or deletion can change the reading frame (the grouping of the codons), resulting in a completely different translation from the original.Copenhagen Harbour BathsHealth geography: Health geography is the application of geographical information, perspectives, and methods to the study of health, disease, and health care.Signal transducing adaptor protein: Signal transducing adaptor proteins are proteins that are accessory to main proteins in a signal transduction pathway. Adaptor proteins contain a variety of protein-binding modules that link protein-binding partners together and facilitate the creation of larger signaling complexes.Phenotype microarray: The phenotype microarray approach is a technology for high-throughput phenotyping of cells.Misattributed paternity: Misattributed paternity is the situation when a child’s putative father is not the child's biological father. Overall, the incidence of misattributed paternity ranges from about 1% to 2%, though it may be considerably higher in certain populations.Disequilibrium (medicine): Disequilibrium}}Molecular evolution: Molecular evolution is a change in the sequence composition of cellular molecules such as DNA, RNA, and proteins across generations. The field of molecular evolution uses principles of evolutionary biology and population genetics to explain patterns in these changes.
