Abstract
Abstract Microsatellites are short tandemly repeated sequences of DNA (commonly referred to as short tandem repeats, STRs ) that are found throughout the genome. They are analyzed by forensic biology laboratories throughout the world as they are highly polymorphic and are amenable to PCR and automation. Microsatellites superseded minisatellites, which are larger repeated units of DNA interspersed throughout the genome and were previously used for forensic DNA analysis.
