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 ... WitrynaVariable number tandem repeat (VNTR): Locations in a genome where a short sequence of nucleotides is repeated adjacent to each other. The length of such a repeat is inherited and is termed functional when it influences gene expression. For 5-HT, the 5-HTT linked polymorphic region (5-HTTLPR) is the most commonly investigated VNTR.

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.
