  2. Locus (genetics) - Wikipedia

    en.wikipedia.org/wiki/Locus_(genetics)

    In genetics, a locus (pl.: loci) is a specific, fixed position on a chromosome where a particular gene or genetic marker is located. [1] Each chromosome carries many genes, with each gene occupying a different position or locus; in humans, the total number of protein-coding genes in a complete haploid set of 23 chromosomes is estimated at ...

  3. Multilocus sequence typing - Wikipedia

    en.wikipedia.org/wiki/Multilocus_sequence_typing

    Multilocus sequence typing (MLST) is a technique in molecular biology for the typing of multiple loci, using DNA sequences of internal fragments of multiple housekeeping genes to characterize isolates of microbial species.

  4. Y-STR - Wikipedia

    en.wikipedia.org/wiki/Y-STR

    If crime scene DNA is ample and all 13 autosomal loci accessible, the likelihood of two unrelated people matching the same sample is around one in one billion. [1] The basis for the profile probability estimation for Y-STR analysis is the counting method. [4] The application of a confidence interval accounts for database size and sampling ...

  5. STR analysis - Wikipedia

    en.wikipedia.org/wiki/STR_analysis

    Short tandem repeat (STR) analysis is a common molecular biology method used to compare allele repeats at specific loci in DNA between two or more samples. A short tandem repeat is a microsatellite with repeat units that are 2 to 7 base pairs in length, with the number of repeats varying among individuals, making STRs effective for human ...

  6. Gene mapping - Wikipedia

    en.wikipedia.org/wiki/Gene_mapping

    There are two distinctive mapping approaches used in the field of genome mapping: genetic maps (also known as linkage maps) [7] and physical maps. [3] While both maps are a collection of genetic markers and gene loci, [8] genetic maps' distances are based on the genetic linkage information, while physical maps use actual physical distances usually measured in number of base pairs.

  7. Multiple loci VNTR analysis - Wikipedia

    en.wikipedia.org/wiki/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".

  8. Chromosome conformation capture - Wikipedia

    en.wikipedia.org/wiki/Chromosome_conformation...

    These methods quantify the number of interactions between genomic loci that are nearby in 3-D space, but may be separated by many nucleotides in the linear genome. [2] Such interactions may result from biological functions, such as promoter - enhancer interactions, or from random polymer looping, where undirected physical motion of chromatin ...

  9. Nuclear mitochondrial DNA segment - Wikipedia

    en.wikipedia.org/wiki/Nuclear_mitochondrial_DNA...

    NUMT insertion into the nuclear genome and its persistence in the nuclear genome is initiated by the physical delivery of mitochondrial DNA to the nucleus. [5] This step follows by the mtDNA integration into the genome through a non-homologous end joining mechanism during the double-strand break (DSB) repair process as envisioned by studying Saccharomyces cerevisiae, [13] [29] and terminates ...
