minisatellite

minisatellite
mini·sat·el·lite -'sat-əl-.īt n any of numerous DNA segments located mainly near the ends of chromosomes that consist of repeating sequences of at least five but usu. not more than 100 nucleotides and that are useful in DNA fingerprinting compare MICROSATELLITE

mini·sat·el·lite (min″e-satґə-līt) any of a series of short (usually 1000 to 5000 base pairs) lengths of DNA dispersed throughout the genome, comprising tandemly repeated nucleotide sequences, each repeating unit composed of approximately 10 to 60 base pairs. Within a genome, different minisatellites may differ in their repeating unit, but the repeating unit within a minisatellite is relatively constant, and the number of repeating units in a given minisatellite varies between individuals in a species. Because of this length polymorphism, minisatellites are sometimes called variable number tandem repeats or variable number of tandem repeats.
