Microsatellite Marker MGI Glossary
Definition
A short (up to several hundred base pairs) segment of DNA that consists of multiple tandem repeats of a two or three base-pair sequence. Microsatellites expand and contract (that is, add or remove repeat units) with a frequency much higher than other types of mutations, making them useful as polymorphic markers in closely related mouse strains.
