Minisatellites

Minisatellite

A minisatellite is a tract of repetitive DNA in which certain DNA motifs (ranging in length from 10 to 60 base pairs) are typically repeated 5-50 times.

Minisatellite: An SSR with a longer motif, up to several dozen basepairs in length. The lower limit has been defined at various values from 6 to 10 bp. For most examples in the literature minisatellite motif-length is 12 bp or more. The upper limit for minisatellite motif-length is not precisely defined. Functional effects of minisatellite SSRs have been investigated much less extensively than have those of microsatellites. Although less abundant, minisatellites share the same fundamental characteristics of frequent repeat number mutations and of repeat number influencing gene function.
