title: DNA secondary structure forming at minisatellite repeat unit sequences.
abstract: The lengths of simple repeat sequences are generally unstable or polymorphic; that is, they are highly variable with respect to the numbers of tandem repeats. To determine the structural features that cause such variability, we examined a minisatellite DNA isolated from the yellow fin sea bream Acanthopagrus latus. Electrophoresis, CD spectra, and calorimetric analyses of oligodeoxyribonucleotides comprised of the minisatellite repeat unit suggest a stable secondary structure is formed within the repeat unit.
