https://en.wikipedia.org/wiki/Loss%20of%20heterozygosity | Loss of heterozygosity (LOH) is a type of genetic abnormality in diploid organisms in which one copy of an entire gene and its surrounding chromosomal region are lost. Since diploid cells have two copies of their genes, one from each parent, a single copy of the lost gene still remains when this happens, but any hetero... |

https://en.wikipedia.org/wiki/Chemotroph | A chemotroph is an organism that obtains energy by the oxidation of electron donors in their environments. These molecules can be organic (chemoorganotrophs) or inorganic (chemolithotrophs). The chemotroph designation is in contrast to phototrophs, which use photons. Chemotrophs can be either autotrophic or heterotrop... |

Statement of the theorem
Let a function be analytic on a closed disc of ... |
https://en.wikipedia.org/wiki/Tandem%20repeat%20locus | Variable number of tandem repeat locus (VNTR locus) is any DNA sequence that exist in multiple copies strung together in a variety of tandem lengths. The number of repeat copies present at a locus can be visualized by means of a Multi-locus or Multiple Loci VNTR Analysis (MLVA). In short, oligonucleotide primers are de... |
