intergenic spacer

intergenic spacer
Abbreviation: IGS
Non-coding DNA separating tandemly arranged copies of a repeated gene sequence (typically ribosomal DNA). Of particular interest because, unlike the coding sequence itself, the spacers show high levels of interspecific sequence polymorphism, and are thus useful as assays for species identification.
