Minisatellites in SCK1/SLI. (A) A schematic diagram of the sequence spanning the SCK1/SLI gene. Exons are represented by boxes either above (top strand) or below (bottom strand) the line. Thirteen putative exons, coding for the Sck protein, were identified by BLAST analysis. The approximate positions of minisatellites, detected by the Tandem Repeats Finder Program (Benson 1999), are indicated by *. At the top, a blown-up portion of the insert shows the relative positions within introns of the 12 minisatellites. (B) The sequences of 12 minisatellite repeat units. Minisatellites 1, 2, 3, 4, 5, 7, 8, 9, 10, 11, and 12 are polymorphic, whereas minisatellites 6 and 7 are monomorphic in the population sample studies.
