microsatellites  

定义

  • Information Microsatellites: segments of DNA characterized by a variable number of copies (typically 5 to 50) of sequence motifs of around two to five bases (referred to as a repeat unit). At any one locus (site in the genome), there are usually several different “alleles” in a population, each allele identifiable by the number of repeat units detected via polymerase chain reaction (PCR). Many microsatellites have a large degree of polymorphism.

范围注释，叙词含义说明

  • In many species, they were the first standard marker technology used to characterize diversity. However, due to their comparatively infrequent presence across the genome, inconsistent reproducibility across laboratories and genotyping platforms, and higher genotyping cost per locus, microsatellites are being replaced by other technologies.
