WitrynaAbstract: DNA repair plays an important role in maintaining the integrity of the genome by repairing DNA damage induced by carcinogens. Certain genetic polymorphisms that occur in DNA-repair genes may affect the ability to repair DNA defects, and may represent a risk factor in carcinogenesis. The gene XRCC1 is involved in DNA repair. WitrynaThe hyperpolymorphism of minisatellite DNA hybridizing with DNA of bacteriophage M13 was analyzed in seven Turkic and Finno-Ugric populations from the Volga-Urals region. In total, hybridization revealed 80 BspRI genomic DNA fragments ranging in size from 1.7 to 10 kb; the average frequency of an individual fragment was 0.299 +/- 0.020.

WitrynaSingle-nucleotide polymorphism. The upper DNA molecule differs from the lower DNA molecule at a single base-pair location (a G/A polymorphism) In genetics, a single-nucleotide polymorphism ( SNP / snɪp /; plural SNPs / snɪps /) is a germline substitution of a single nucleotide at a specific position in the genome and is present … WitrynaA single nucleotide polymorphism, or SNP (pronounced "snip"), is a variation at a single position in a DNA sequence among individuals. Recall that the DNA sequence is formed from a chain of four ... WitrynaIn molecular biology, restriction fragment length polymorphism (RFLP) is a technique that exploits variations in homologous DNA sequences, known as polymorphisms, in order to distinguish individuals, populations, or species or to pinpoint the locations of genes within a sequence.

WitrynaAbstract. The current predominant method of analyzing base substitution polymorphisms, RFLP analysis, is likely to be gradually supplanted by methods based on PCR because of the improved sensitivity and genotyping rate. The most promising PCR methods for analysis appear to be allele-specific PCR and single-stranded conformational analysis.
