This approach is limited by the fact that semi-quantitative PCR methods do not work well using microsatellites, so only cases in which the allele lengths of the microsatellites differ over chromosomal region of …

Microsatellites and their application to population genetic studies

Web3. DNA regions with repeat units that are 2–6 bp in length are called microsatellites, simple sequence repeats (SSRs), or short tandem repeats (STRs). STRs have become popular DNA repeat markers because they are easily amplified by the Polymerase Chain Reaction(PCR) without the problems of differential amplification. WebMicrosatellites are useful markers at a wide range of scales of analysis. Until recently, they were the most important tool in mapping genomes -- such as the widely publicized mapping of the human genome. They … port is the left side of a ship
