Variable-number  tandem  repeats  (VNTRs,  or
   minisatellites)  contain repeating clusters of 10-100 nucleotides that
   are   variable   between   individuals,   and  may  produce  different
   restriction fragments.

   Even though one band (B2) is shared between 2 individuals in this RFLP
   analysis  of many VNTR markers (this example shows just 2 markers) can
   serve as a DNA fingerprint to identify individuals.

   Relatively  large  sample  of  DNA (10,000 cells) is required for VNTR
   analysis,  so  this technoqie is more useful in paternity testing than
   in criminal cases.
