*Minisatellites are the repeated DNA sequences at a defined locus with each repeat unit usually consisting of about 10 - 100 base pairs and the array spanning from 0.5-100 kb. VNTRs which stands for “Variable Number of Tandem Repeats” are a type of minisatellite. VNTRs are most commonly used for DNA fingerprinting.
